A 4-MONTH-OLD HISPANIC INFANT was brought to her pediatrician by her parents for evaluation of a dark red lesion over her right eyelid. The mother said that the lesion appeared when the child was 4 weeks old and started as a small red dot. As the baby grew, so did the red dot. The mother said the lesion appeared redder and darker when the baby got fussy and cried. The mother noted that some of the child’s eyelashes on the affected eyelid had fallen out. The infant was still able to use her eyes to follow the movements of her parents and siblings.

The mother denied any complications during pregnancy and delivered the child vaginally. No one else in the family had a similar lesion. When asked, the mother said that when her daughter was born, she was missing hair on her scalp and had dark spots on her lower backside. The mother had taken the baby to all wellness checks. The child was up to date on her vaccines, had no known drug allergies, and was otherwise healthy.

The pediatrician referred the baby to our skin clinic for further evaluation and treatment of the right eyelid lesion. Skin examination showed a 2.1-cm focal/localized, vascular, violaceous/dark red plaque over the right upper eyelid with an irregular border causing mild drooping of the right eyelid and some missing eyelashes (FIGURE 1). Multiple hyperpigmented patches on the upper and lower back were clinically consistent with Mongolian spots. Hair thinning was observed on the posterior and left posterior scalp.

Diagnosis: Infantile hemangioma

The diagnosis of an infantile hemangioma was made clinically, based on the lesion’s appearance and when it became noticeable (during the child’s first few weeks of life).

The majority of infantile hemangiomas do not require treatment because they can resolve spontaneously over time.

Infantile hemangiomas are the most common benign tumors of infancy, and the majority are not present at birth.^1,2 Infantile periocular hemangioma, which our patient had, is typically unilateral and involves the upper eyelid.¹ Infantile hemangiomas appear in the first few weeks of life with an area of pallor and later a faint red patch, which the mother first noted in our patient. Lesions grow rapidly in the first 3 to 6 months.² Superficial lesions appear as bright red papules or patches that may have a flat or rough surface and are sharply demarcated, while deep lesions tend to be bluish and dome shaped.^1,2 

Infantile hemangiomas continue to grow until 9 to 12 months of age, at which time the growth rate slows to parallel the growth of the child. Involution typically begins by the time the child is 1 year old. Most infantile hemangiomas do not improve significantly after 3.5 years of age.³

Differential includes congenital hemangiomas, pyogenic granulomas

Clinical presentation, histology, and lesion evolution distinguish infantile hemangioma from other diagnoses, notably the following:

Congenital hemangiomas (CH) are fully formed vascular tumors present at birth; they occur less frequently than infantile hemangiomas. CHs are divided into 2 categories: rapidly involuting CHs and noninvoluting CHs.⁴

Continue to: Pyogenic granulomas

Pyogenic granulomas are usually small (< 1 cm), sessile or pedunculated red papules or nodules. They are friable, bleed easily, and grow rapidly.

Capillary malformations can manifest at birth as flat, red/purple, cutaneous patches with irregular borders that are painless and can spontaneously bleed; they can be found in any part of the body but mainly occur in the cervicofacial area.⁵ Capillary malformations are commonly known as stork bites on the nape of the neck or angel kisses if found on the forehead. Lateral lesions, known as port wine stains, persist and do not resolve without treatment.⁵

Tufted angioma and kaposiform hemangioendothelioma manifest as expanding ecchymotic firm masses with purpura and accompanying lymphedema.⁴ Magnetic resonance imaging, including magnetic resonance angiography, is recommended for management and treatment.⁴ 

Venous malformations can be noted at birth as a dark blue or purple discoloration and manifest as a deep mass.⁵ Venous malformations grow with the patient and have a rapid growth phase during puberty, pregnancy, or traumatic injury.⁵ 

Arteriovenous malformations (AVMs) may be present at birth as a slight blush hypervascular lesion. AVMs can be quiescent for many years and grow with the patient. AVMs have a palpable warmth, pulse, or thrill due to high vascular flow.⁵

Individualize treatment when it’s needed

The majority of infantile hemangiomas do not require treatment because they can resolve spontaneously over time.² That said, children with periocular infantile hemangiomas may require treatment because the lesions may result in amblyopia and visual impairment if not properly treated.⁶ Treatment should be individualized, depending on the size, rate of growth, morphology, number, and location of the lesions; existing or potential complications; benefits and adverse events associated with the treatment; age of the patient; level of parental concern; and the physician’s comfort level with the various treatment options.

Predictive factors for ocular complications in patients with periocular infantile hemangiomas are diameter > 1 cm, a deep component, and upper eyelid involvement. Patients at risk for ocular complications should be promptly referred to an ophthalmologist, and treatment should be strongly considered.⁶ Currently, oral propranolol is the treatment of choice for high-risk and complicated infantile hemangiomas.² This is a very safe treatment. Only rarely do the following adverse effects occur: bronchospasm, bradycardia, hypotension, nightmares, cold hands, and hypoglycemia. If these adverse effects do occur, they are reversible with discontinuation of propranolol. Hypoglycemia can be prevented by giving propranolol during or right after feeding.

Our patient was started on propranolol 1 mg/kg/d for 1 month. The medication was administered by syringe for precise measurement. After the initial dose was ­tolerated, this was increased to 2 mg/kg/d ­for 1 month, then continued sequentially another month on 2.5 mg/kg/d, 2 months on 3 mg/kg/d, and finally 2 months on 3.4 mg/kg/d. All doses were divided twice per day between feedings.

After 7 months of total treatment time (FIGURE 2), we began titrating down the patient’s dose over the next several months. After 3 months, treatment was stopped altogether. At the time treatment was completed, only a faint pink blush remained.

SAN DIEGO – As with many markers for the evaluation of challenging melanocytic lesions, preferentially expressed antigen in melanoma (PRAME) has its benefits and drawbacks, according to Cora Humberson, MD.

“I’m a fan, but there are issues with it,” Dr. Humberson, dermatopathology coordinator in the department of pathology at Scripps MD Anderson Cancer Center, San Diego, said at the annual Cutaneous Malignancy Update. “It’s all in how you use it.”

PRAME is part of the cancer/testis (CT) antigens, of which more than 40 have now been identified. They are encoded by genes that are normally expressed only in the human germ line, but are also expressed in various tumor types, including melanoma and carcinomas of the bladder, lung, and liver. “The biological function of these antigens is not fully understood, but they may act as a repressor of retinoic acid, potentially inhibiting differentiation, inhibiting proliferation arrest – things that we associate with malignancy,” she said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. “These immunogenic proteins are being pursued as targets for therapeutic cancer vaccines,” she noted.

CT antigens are also being evaluated for their role in oncogenesis, she added. Recapitulation of portions of the germline gene-expression might contribute characteristic features to the neoplastic phenotype, including immortality, invasiveness, immune evasion, and metastatic capacity.

According to Dr. Humberson, PRAME can be used to differentiate comingled nevus and melanoma, to distinguish between nevoid melanoma and nevus, and for melanoma margin assessment in sun-damaged skin. One potential pitfall is that sun-damaged melanocytes may express PRAME. “The older the person and the more sun damage [they have], the more likely you are to see this, but the melanocytes won’t be grouped, they’ll be scattered,” she said.

Another pitfall is that less than 15% of nevi may express PRAME. “PRAME can be expressed in scars, so if you’re looking at a spindle cell lesion, be aware that you might be looking at a scar if you’re seeing PRAME expression,” she added. She also noted that PRAME immunohistochemistry (IHC) expression is not a prognostic biomarker in thin melanomas.

If fewer than 25% of cells in a melanocytic lesion express PRAME, most published assessments of PRAME IHC favor nevi as the diagnosis. “If more than 75% are expressing it, it favors melanoma,” Dr. Humberson said. “There’s a big category in between. It’s not that 30% is more likely benign or that 60% is more likely malignant; you can’t really depend upon [PRAME] if you’re in this range.”

A diagnostic accuracy study found that when more than 75% of cells express PRAME, the marker has a sensitivity of 0.63 and a specificity of 0.97.

Selected PRAME-related published references she recommended include: J Cutan Pathol. 2021;48(9):1115-23; Diagnostics. 2022 Sep 9; 12(9):2197, and J Cutan Pathol. 2022;49(9):829-32.

Dr. Humberson reported having no relevant disclosures.

A skin scraping and potassium hydroxide (KOH) prep confirmed the presence of branching hyphae, consistent with tinea corporis. The large size of this plaque could have easily made this diagnosis more difficult. When tinea corporis is suspected, look at the edge of the plaque; there is often thin scale and sometimes small pustules corresponding to follicular involvement.

Commonly called by the misnomer “ringworm,” tinea corporis is a skin infection caused by a wide variety of dermatophytes and affects all ages, sexes, and skin types. Trichophyton, Microsporum, and Epidermophyton species are frequently isolated.¹ Patients with atopic dermatitis or weakened immunity may be more susceptible to more frequent or long-lasting episodes. Diabetes may have contributed to the extent of the disease in this case.

Patients with tinea corporis present with one or several annular patches to plaques that grow in size. When the source of contagion is an animal, inflammation can be dramatic. In the case above, there was minimal to no itching and the patient didn’t notice the rash; thus, it was able to enlarge for months.

Treatment options include systemic and topical antifungal therapy. Consideration should be given to the severity of the disease and causal organism. Azoles, terbinafine, and ciclopirox are common treatment options. Topical therapy with an appropriately selected antifungal for 1 to 6 weeks, based on clinical response, is safe and effective. It is important to consider other foci of infection, including the feet and hands. More extensive disease may be treated with oral therapy such as terbinafine, fluconazole, or itraconazole.

Because of the extent of the disease and the challenge of effective coverage with topical therapy, this patient was treated with oral terbinafine 250 mg daily for 3 weeks. The plaque cleared completely.

THE COMPARISON

A Vitiligo in a young Hispanic female, which spared the area under a ring. The patient has spotty return of pigment on the hand after narrowband ultraviolet B (UVB) treatment.

B Vitiligo on the hand in a young Hispanic male.

Vitiligo is a chronic autoimmune disorder characterized by areas of depigmented white patches on the skin due to the loss of melanocytes in the epidermis. Various theories on the pathogenesis of vitiligo exist; however, autoimmune destruction of melanocytes remains the leading hypothesis, followed by intrinsic defects in melanocytes.¹

Vitiligo is associated with various autoimmune diseases but is most frequently reported in conjunction with thyroid disorders.²

Vitiligo affects approximately 1% of the US population and up to 8% worldwide.² There is no difference in prevalence between races or genders. Females typically acquire the disease earlier than males. Onset may occur at any age, although about half of patients will have vitiligo by 20 years of age.¹

Key clinical features in people with darker skin tones

Bright white patches are characteristic of vitiligo. The patches typically are asymptomatic and often affect the hands (FIGURES A and B), perioral skin, feet, and scalp, as well as areas more vulnerable to friction and trauma, such as the elbows and knees.² Trichrome lesions—consisting of varying zones of white (depigmented), lighter brown (hypopigmented), and normal skin—are most commonly seen in individuals with darker skin. Trichrome vitiligo is considered an actively progressing variant of vitiligo.²

An important distinction when making the diagnosis is evaluating for segmental vs nonsegmental vitiligo. Although nonsegmental vitiligo—the more common subtype—is characterized by symmetric distribution and a less predictable course, segmental vitiligo manifests in a localized and unilateral distribution, often avoiding extension past the midline. Segmental vitiligo typically manifests at a younger age and follows a more rapidly stabilizing course.³

Worth noting

Given that stark contrasts between pigmented and depigmented lesions are more prominent in darker skin tones, vitiligo can be more socially stigmatizing and psychologically devastating in these patients.^4,5

Treatment of vitiligo includes narrowband UVB (NB-UVB) light phototherapy, excimer laser, topical corticosteroids, topical calcineurin inhibitors such as tacrolimus and pimecrolimus, and surgical melanocyte transplantation.¹ In July 2022, ruxolitinib cream 1.5% was approved by the US Food and Drug Administration (FDA) for nonsegmental vitiligo in patients ages 12 years and older.^6,7 It is the only FDA-approved therapy for vitiligo. It is thought to work by inhibiting the Janus kinase–signal transducers and activators of the transcription pathway.⁶ However, topical ruxolitinib is expensive, costing more than $2000 for 60 g.⁸

Health disparity highlight

A 2021 study reviewing the coverage policies of 15 commercial health care insurance companies, 50 BlueCross BlueShield plans, Medicaid, Medicare, and Veterans Affairs plans found inequities in the insurance coverage patterns for therapies used to treat vitiligo. There were 2 commonly cited reasons for denying coverage for therapies: vitiligo was considered cosmetic and therapies were not FDA approved.⁷ In comparison, NB-UVB light phototherapy for psoriasis is not considered cosmetic and has a much higher insurance coverage rate.^9,10 The out-of-pocket cost for a patient to purchase their own NB-UVB light phototherapy is more than $5000.¹¹ Not all patients of color are economically disadvantaged, but in the United States, Black and Hispanic populations experience disproportionately higher rates of poverty (19% and 17%, respectively) compared to their White counterparts (8%).¹²

Final thoughts

FDA approval of new drugs or new treatment indications comes after years of research discovery and large-scale trials. This pursuit of new discovery, however, is uneven. Vitiligo has historically been understudied and underfunded for research; this is common among several conditions adversely affecting people of color in the United States.¹³

Vitiligo is a chronic autoimmune disorder characterized by areas of depigmented white patches on the skin due to the loss of melanocytes in the epidermis. Various theories on the pathogenesis of vitiligo exist; however, autoimmune destruction of melanocytes remains the leading hypothesis, followed by intrinsic defects in melanocytes.¹

ORLANDO – Research on pigmentary disorders has entered an overdue era of increased attention, resulting in more treatment options and the promise of improved quality of life for patients, a panel of experts said in a session on this topic at the ODAC Dermatology, Aesthetic & Surgical Conference.

The arrival of ruxolitinib cream, a topical JAK inhibitor – and oral JAK inhibitors, including ritlecitinib, a JAK3/TEC (tyrosine kinase expressed in hepatocellular carcinoma) inhibitor in clinical trials – is a welcome development for treatment of vitiligo, said John E. Harris, MD, PhD, chair of dermatology and director of the Vitiligo Clinic and Research Center at the University of Massachusetts, Worcester. Also in the pipeline is a kit for melanocyte-keratinocyte transplantation, which involves transplanting epidermal cells from one part of the body to another. This can be a challenging procedure but a kit would make it easier for a wider range of practitioners. (Topical ruxolitinib was approved by the Food and Drug Administration for treating nonsegmental vitiligo in July, 2022.)

“In the last 10 years, it’s just blown up and people care about vitiligo now,” Dr. Harris said, noting that vitiligo is more than a cosmetic issue, like gray hair or wrinkles. “Vitiligo is an autoimmune disease and now is being treated as such.”

Nada Elbuluk, MD, MSc, associate professor of dermatology at the University of Southern California, Los Angeles, said she’s pleased at the increasing availability of treatment options for hyperpigmentation, aside from hydroquinone, which is associated with an increased risk of adverse effects.

“We have more and more nonhydroquinone agents ... which is really nice because it expands our treatment armamentarium and what we can use to cycle people off of hydroquinone,” she said.

Some of these options include tranexamic acid and products containing azelaic acid or vitamin C.

Iltefat H. Hamzavi, MD, senior staff physician at Henry Ford Health System, Detroit, said that pigmentary disorders are receiving the recognition they deserve.

“I’m excited just about the intersection of society and science, the awareness that pigmentary abnormalities mean something, and they mean something across our society,” he said.

Dr. Elbuluk said that hyperpigmentation has “profound effects on quality of life” for patients.

“They are often more bothered by the darkening of the skin than the primary process that caused it,” she said. “It’s not uncommon that the chief complaint will say ‘dark spots’ and I walk in a room and it’s a patient who has acne. They don’t even say they’re here for acne. They just put ‘dark spots’ [down] because that’s what bothers them. That’s what lasts for so long after the acne is gone.”

The experts offered suggestions for managing these cases. Among her tips, Dr. Elbuluk said that for hyperpigmentation, physicians should not be afraid to biopsy the face – but suggested small, 2-millimeter specimens. In addition, “you can get common conditions in uncommon places,” she noted. “If you see something that looks like melasma off the face, it actually could be, so keep that in your differential.”

Dr. Hamzavi, who spoke about hypopigmentation disorders, said clinicians need to use an algorithm for diagnosis, considering features such as localized or diffuse, scale or no scale, as well as patient history, and other factors. For instance, a hypopigmented area that is localized and has a reddish central papule might lead a clinician to a diagnosis of hypopigmented sarcoidosis.

Using the algorithms, “you actually have to categorize these and then use your own experience. ... All of these elements can help you become a really good taxonomist – ultimately that’s what physicians are.”

He said it’s also important to know when it’s time to reconsider a diagnosis, such as when patients do not respond to traditional treatments. “If they don’t respond, re-categorize,” he said.

Speaking about vitiligo, Dr. Harris said it’s crucial to differentiate active vitiligo from inactive vitiligo and if it’s active, steps need to be taken to keep it from worsening..

Four signs of active vitiligo are a “confetti” pattern of clustered tiny macules of depigmentation, which will coalesce quickly into huge patches; tri-chrome vitiligo that includes a hypopigmented zone; linear areas of depigmentation (Koebner’s phenomenon) that look like scratches on the skin; and inflammatory vitiligo, with an erythematous ring around the edges of a depigmented area.

SAN DIEGO – After Arisa E. Ortiz, MD, and colleagues published results of a multicenter study reporting that one treatment with the long-pulsed 1,064-nm Nd:YAG laser cleared nonaggressive basal cell carcinoma (BCC) on the trunk and extremities in 90% of patients, she heard from colleagues who were skeptical of the approach.

Maybe it’s just the biopsy alone that’s clearing these tumors, some told her. Others postulated that since the energy was delivered with a 5- to 6-mm spot size at a fluence of 125-140 J/cm² and a 7- to 10-ms pulse duration, bulk heating likely disrupted the tumors. However, treatments were generally well tolerated, required no anesthesia, and caused no significant adverse events.

“It’s almost scarless,” Dr. Ortiz, director of laser and cosmetic dermatology at the University of California, San Diego, said at the annual Masters of Aesthetics Symposium. “Sometimes the treatment does leave a mark, but I think the scars are always acceptable. We do have good histologic evidence that we can penetrate 2.15 mm, which is a lot deeper than what the pulsed-dye laser or other superficial wavelengths are able to penetrate.”

Data is well powered to reject the null hypothesis that laser treatment does not have an effect on nodular and superficial BCC lesions, she continued, noting that it is at least comparable if not superior with clearance rates reported for methyl aminolevulinate–PDT (73%), imiquimod cream (83%), and fluorouracil cream (80%). “Maybe we’re not specifically targeting the vasculature [with this approach], but we did some optical coherence tomography imaging and saw that the blood vessels in the tumor were coagulated while the vasculature in the surrounding normal skin were spared,” said Dr. Ortiz, who is also vice president of the American Society for Laser Medicine and Surgery.

In a more recent analysis, she and her colleagues retrospectively analyzed long-term outcomes in 11 patients with BCC who had 16 lesions treated with the 1,064-nm Nd:YAG laser. At a mean of 9 months, 100% of lesions remained clear as determined by clinical observation.

In a subsequent, as yet unpublished study, she and her collaborators followed 34 patients with BCC one year following laser treatment. “Of these, 33 had no recurrence at 1-year follow-up,” Dr. Ortiz said, noting that the one patient with a recurrence was on a biologic agent for Crohn’s disease.

One key advantage of using the long-pulsed 1,064-nm Nd:YAG laser for nonaggressive BCC is the potential for one treatment visit. “They don’t have to come back for suture removal,” she said. “It’s a quick procedure, takes only about 5 minutes. There’s no limitation on activity and there’s minimal wound care, light ointment, and a band-aid; that’s it.”

In addition, she said, there is a lower risk of complications, infections, and bleeding, and there is minimal scarring. It is “also an alternative for treating patients with multiple tumors or those who are poor surgical candidates, such as the elderly and those with Gorlin syndrome.”

Dr. Ortiz avoids treating aggressive subtypes “because we don’t know what margin to treat,” she added. “Avoid the face. I do make some exceptions for patients if they’re elderly or if they’ve had multiple tumors. Monitor for recurrence like you would using any other modality.”

She uses lidocaine without epinephrine to avoid vasoconstriction and treats with the 1,064-nm Nd:YAG laser as follows: a 5-mm spot size, a fluence of 140 J/cm², and a pulse duration of 8 ms, with no cooling, which are the settings for the Excel V Laser System, she noted. “If you’re using a different Nd:YAG laser, your pulse duration may vary. I do let the device cool in between pulses to avoid bulk heating.”

The immediate endpoint to strive for is slight greying and slight contraction, and the procedure is covered by insurance, billed as malignant destruction/EDC (CPT codes 17260-17266 trunk and 17280-17283 face). “I do biopsy prior to treatment,” she said. “I like the biopsy to be healed when I’m using the laser, so I’ll treat them about a month later.”

As for future directions, Dr. Ortiz and colleagues plan to evaluate the use of gold nanoparticles to more selectively target BCC during treatment with the 1,064-nm Nd:YAG laser. For now, she sees no downside of the procedure for proper candidates. “I do think that patients really like it,” she said. “It’s effective and easy.”

Dr. Ortiz disclosed having financial relationships with several pharmaceutical and device companies. She is also cochair of the MOAS.

Maybe it’s just the biopsy alone that’s clearing these tumors, some told her. Others postulated that since the energy was delivered with a 5- to 6-mm spot size at a fluence of 125-140 J/cm² and a 7- to 10-ms pulse duration, bulk heating likely disrupted the tumors. However, treatments were generally well tolerated, required no anesthesia, and caused no significant adverse events.

“It’s almost scarless,” Dr. Ortiz, director of laser and cosmetic dermatology at the University of California, San Diego, said at the annual Masters of Aesthetics Symposium. “Sometimes the treatment does leave a mark, but I think the scars are always acceptable. We do have good histologic evidence that we can penetrate 2.15 mm, which is a lot deeper than what the pulsed-dye laser or other superficial wavelengths are able to penetrate.”

Data is well powered to reject the null hypothesis that laser treatment does not have an effect on nodular and superficial BCC lesions, she continued, noting that it is at least comparable if not superior with clearance rates reported for methyl aminolevulinate–PDT (73%), imiquimod cream (83%), and fluorouracil cream (80%). “Maybe we’re not specifically targeting the vasculature [with this approach], but we did some optical coherence tomography imaging and saw that the blood vessels in the tumor were coagulated while the vasculature in the surrounding normal skin were spared,” said Dr. Ortiz, who is also vice president of the American Society for Laser Medicine and Surgery.

In a more recent analysis, she and her colleagues retrospectively analyzed long-term outcomes in 11 patients with BCC who had 16 lesions treated with the 1,064-nm Nd:YAG laser. At a mean of 9 months, 100% of lesions remained clear as determined by clinical observation.

In a subsequent, as yet unpublished study, she and her collaborators followed 34 patients with BCC one year following laser treatment. “Of these, 33 had no recurrence at 1-year follow-up,” Dr. Ortiz said, noting that the one patient with a recurrence was on a biologic agent for Crohn’s disease.

One key advantage of using the long-pulsed 1,064-nm Nd:YAG laser for nonaggressive BCC is the potential for one treatment visit. “They don’t have to come back for suture removal,” she said. “It’s a quick procedure, takes only about 5 minutes. There’s no limitation on activity and there’s minimal wound care, light ointment, and a band-aid; that’s it.”

In addition, she said, there is a lower risk of complications, infections, and bleeding, and there is minimal scarring. It is “also an alternative for treating patients with multiple tumors or those who are poor surgical candidates, such as the elderly and those with Gorlin syndrome.”

Dr. Ortiz avoids treating aggressive subtypes “because we don’t know what margin to treat,” she added. “Avoid the face. I do make some exceptions for patients if they’re elderly or if they’ve had multiple tumors. Monitor for recurrence like you would using any other modality.”

She uses lidocaine without epinephrine to avoid vasoconstriction and treats with the 1,064-nm Nd:YAG laser as follows: a 5-mm spot size, a fluence of 140 J/cm², and a pulse duration of 8 ms, with no cooling, which are the settings for the Excel V Laser System, she noted. “If you’re using a different Nd:YAG laser, your pulse duration may vary. I do let the device cool in between pulses to avoid bulk heating.”

The immediate endpoint to strive for is slight greying and slight contraction, and the procedure is covered by insurance, billed as malignant destruction/EDC (CPT codes 17260-17266 trunk and 17280-17283 face). “I do biopsy prior to treatment,” she said. “I like the biopsy to be healed when I’m using the laser, so I’ll treat them about a month later.”

As for future directions, Dr. Ortiz and colleagues plan to evaluate the use of gold nanoparticles to more selectively target BCC during treatment with the 1,064-nm Nd:YAG laser. For now, she sees no downside of the procedure for proper candidates. “I do think that patients really like it,” she said. “It’s effective and easy.”

Dr. Ortiz disclosed having financial relationships with several pharmaceutical and device companies. She is also cochair of the MOAS.





 

Data from a dermatology monkeypox (mpox) registry reveal that patients struck during the 2022 worldwide outbreak experienced two nontraditional findings: Skin lesions that frequently appeared before systemic illness and a much lower overall numbers of lesions.

“Just these two findings alone show how important it is to remain clinically vigilant as dermatologists,” Esther Freeman, MD, PhD, director of global health dermatology at Massachusetts General Hospital, Boston, said in an interview. She is the corresponding author of the study, which analyzed 101 mpox cases from 13 countries and was published online on in the Journal of the American Academy of Dermatology.

“Mpox appeared to manifest differently than in previous outbreaks with morphologic and clinical evolutions much different than previously reported in endemic and prior outbreaks,” added Dr. Freeman. “Dermatologists should continue to keep mpox on the differential as it continues to circulate at low levels in the population and is a mimicker of many other common skin diseases.”

According to the Centers for Disease Control and Prevention, as of Jan. 20, 2023, there have been 30,061 cases of mpox in the United States during the outbreak that began in 2022; 23 people died. Worldwide, the number of cases neared 85,000.

In contrast to past outbreaks where patients may have had dozens or hundreds of lesions, 20% had only 1 lesion, while 52% had 2-5 lesions, and 20% had 6-20 lesions. “There may be only a few lesions, so index of suspicion needs to be high,” Dr. Freeman said.

According to the study, “the most common skin lesion morphologies and secondary characteristics reported included papules, vesicles/blisters, pustules, erosions/ulcers and crust/scabs.” Dr. Freeman cautioned that “lesions may not go through the ‘typical’ progression from papule to pustule. The initial lesion could even be an ulceration or a crust. For dermatologists, this means you need to have a high index of suspicion, especially if you see a new onset lesion in the groin or perianal area, though they can also start elsewhere.”

She added that “the lesion you see on exam could be a classic pustule/pseudopustule, but it might not be – it could be a small perianal erosion or ulceration. If you have any concern it could be mpox, it’s a good idea to test by PCR.”

 

Morbilliform rash, scarring reported

The study also highlighted 10 cases of morbilliform rash. “A morbilliform exanthem is pretty nonspecific, and usually cases of mpox have more specific features,” dermatologist and study coauthor Misha Rosenbach, MD, of the University of Pennsylvania, Philadelphia, said in an interview.

“Given the current low rates of mpox, I do not think most dermatologists need to worry about mpox when evaluating morbilliform exanthems. However, in high-risk patients or patients with other morphologies, it is worth noting that there’s a chance that this may be related.”

Emory University dermatologist Howa Yeung, MD, MSc, who wasn’t involved with the study, said in an interview that morbilliform rashes in the mouth/tongue area, mostly on days 1-5, should be considered a possible sign of mpox. “While I didn’t typically think of monkeypox virus as a cause of viral exanthems, I will now add it to my differential diagnoses.”

Pediatric patients with atopic dermatitis (AD) are more likely to experience symptoms at classical sites such as the knees and have more associated and severe signs of AD, while older adults tend to present with less flexural eczema and the fewest associated signs.

Those are key findings from a study conducted at a single academic medical center, which aimed to identify the age-related clinical phenotypes of AD.

“Previous studies have found differences in the clinical characteristics of AD depending on age of AD onset, ethnic background, and AD severity,” senior author Jonathan I. Silverberg, MD, PhD, MPH, director of clinical research in the department of dermatology at George Washington University, Washington, and his coauthor wrote in the study, which was published online in JAAD International. “However, none have prospectively compared the clinical characteristics and associated signs by age group. Improved understanding of the clinical phenotypes of AD may help guide choice of treatment and improve health outcomes,” they added.

Along with coauthor Sheena Chatrath, a dermatology research fellow in the department, Dr. Silverberg prospectively reviewed self-reported questionnaires that were completed by 380 patients prior to their visit at GWU’s eczema clinic between 2013 and 2019. Questions included age of AD onset, sociodemographics, Visual Analog Scale (VAS) itch and sleep for Scoring AD, and Numeric Rating Scale (NRS) for skin pain and itch. The researchers used the Eczema Area Severity Index to assess AD severity and a dermatologist conducted full body skin exams, noting the distribution of AD involvement as well as associated signs.

Of the 380 patients, 6.1% were younger than aged 18 years, 46.3% were young adults aged 18-39 years, and 47.6% were older adults 40 years of age and older.

Compared with pediatric patients, both young and older adults were less likely to experience AD on the ankles (adjusted odds ratio [aOR], 0.41 and 0.43, respectively), moderate to severe AD lesions on flexures (aOR, 0.47 and 0.30), pityriasis alba (aOR, 0.24 and 0.07), oozing lesions (aOR, 0.44 and 0.35), and moderate to severe excoriations (aOR, 0.49 and 0.44).

In children, severe itch was more common, reported in 47.1%, compared with 43.4% of the young adults and 38.6% of the older adults, and itch was less severe among the young and older adults. “Interestingly, despite increased itch in pediatric patients, we found no difference in the severity of skin pain across all age groups,” the researchers wrote. “Moreover, pediatric patients reported skin pain less often than adult patients. This may be due to age-related differences of pain perception.”

In other findings, compared with pediatric patients, young adults were more likely to experience AD around the eyes (aOR, 2.92), while older adults were less likely to experience AD on elbows (aOR, 0.34), nipples (aOR, 0.40), knees (aOR, 0.27), and less likely to have keratosis pilaris (aOR, 0.38), and lichenification (aOR, 0.47).

Dr. Silverberg and Ms. Chatrath used latent class analysis to identify four classes for distribution of AD lesions. In this model, class 1 had low probabilities of AD involvement at all sites examined and class 2 had low probabilities of scalp, face, and foot involvement, and intermediate probability of all other AD sites. Class 3 had low probabilities of hand and foot involvement, high probability of facial erythema, and intermediate probability of all other AD signs, while class 4 had intermediate probability of postauricular and foot involvement, and high probability of all other AD sites examined.

“Pediatric patients were most commonly in class 4 (33.3%), followed by class 1 and 2 (26.7%), and least commonly in class 3 (13.3%),” the authors wrote. “In young adults, class 4 and 1 were most common (32.4% and 29.4%), followed by class 2 (27.9%), and least commonly class 3 (10.3%). In older adults, class 1 was most common (40.3%), followed by class 4 (23.6%), and least commonly classes 2 and 3 (18.1%).”

The researchers also used latent class analysis to identify four classes for the signs and symptoms of AD. In this model, class 1 had zero-low probability of all AD signs and class 2 had low probability of all AD signs. Class 3 had high probability of oozing lesions and low probability of all other signs, while class 4 had high probability of xerosis, intermediate probability of ichthyosis and palmar hyperlinearity, and low probability of all other AD signs.

In all three groups, the most common class was class 1 (85.6% of older adults, 81.8% of younger adults, and 82.6% of pediatric patients). Among the pediatric patients, they wrote, “class 3 was the second most common (8.7%), followed by class 2 and 4 (4.4%).” Among the young adults, 9.7% were in class 2, 5.7% were in class 4, and 2.8% were in class 3; and among the older adults, 8.3% were in class 4, 4.4% were in class 2, and 1.67% were in class 3.

Zelma Chiesa Fuxench, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, who was asked to comment on the study, said that while AD is traditionally largely thought of as a disease of children primarily involving the flexural areas, “this study provides additional evidence to support that AD is more than just a disease of childhood with a fixed clinical presentation, but is a heterogeneous disease whose clinical presentation varies across different population groups.”

A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.

HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.

Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.

The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.

The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.

Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”

“Examination alone is not sufficient to evaluate early changes, and specialized testing must be done. These include color photos, visual field tests, optical coherence tomography, fundus autofluorescence and in some cases, multifocal electroretinogram. Also, the AAO [American Academy of Ophthalmology] has specific recommendations related to Asian patients as they may have a different pattern of retinopathy that must also be considered.”
 

More accurate risk measurements

This news organization asked study coauthor April Jorge, MD, assistant professor of medicine in the division of rheumatology, allergy, and immunology at Massachusetts General Hospital and Harvard Medical School, Boston, to discuss the study, how it correlates to past research, and what it adds that’s new and useful to rheumatologists and ophthalmologists:

Question: Your research found that a higher dose of HCQ in the first 5 years of treatment led to a greater risk of retinopathy. Is there any indication that a lower dose given more frequently, either within that 5-year period or longer, would pose a similar risk?

Answer: In our study, we assessed the HCQ dose in the first 5 years of use but followed patients who continued the medication longer than 5 years, through up to 15 years of use. Therefore, we compared the risk of HCQ retinopathy associated with different HCQ dosages but for the same duration of use. We found that for any dose of HCQ, the risk of retinopathy increases the longer the medication is used. However, patients who used a higher dose of HCQ had a higher risk of developing retinopathy over time.

Also unique to our study, we graded the severity of HCQ retinopathy outcomes. This was important, as we found that the majority of retinopathy cases detected through routine screening are mild and presumed to be asymptomatic. This will likely be reassuring news for patients that we can screen for this adverse event to detect it early and prevent vision loss.

Another important difference was that we assessed the risk of retinopathy associated with using over 6 mg/kg per day, between 5 and 6 mg/kg per day, and less than 5 mg/kg per day, whereas the highest dosing group assessed in the 2014 study included all patients using over 5 mg/kg per day. The risk was considerably higher in the > 6 mg/kg per day group than in the 5-6 mg/kg per day group.

Q: How can rheumatologists and ophthalmologists use this new information specifically to better treat their patients?

A: Our study provides more accurate estimates of the risk of HCQ retinopathy than in prior studies. These risk estimates can be used when rheumatologists (and other clinicians who prescribe HCQ) consider the risks and benefits of this otherwise important and well-tolerated medication. The risk associated with different dose ranges could also inform dosing decisions, since dosing over 6 mg/kg per day may be more of a concern than using doses in the 5-6 mg/kg range. Ophthalmologists can also use these new risk estimates to counsel patients of the importance of HCQ retinopathy screening and can also hopefully provide some reassurance to patients that the risk of severe retinopathy is low as long as they are being monitored.

A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.

HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.

Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.

The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.

The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.

Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”

Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.

Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.^1,2

This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.³ In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.⁴ Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.¹

What’s the differential diagnosis?

The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.

Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.
