Depigmented plaques on vulva

Author and Disclosure Information

The distinctive pattern of our young patient’s skin changes made the diagnosis clear.



A mother brought her 8-year-old daughter to our office for evaluation of vitiligo “down there” (FIGURE). The skin eruption first appeared on her vulva a year earlier and was intermittently pruritic. The lesions were initially smaller and red, but had since lightened in color, coalesced, and had begun to spread to the perianal area. The patient’s mother had received a call from her daughter’s teacher who observed that her daughter was scratching the area and might be masturbating in class.

The mother reported that 6 months earlier, her daughter had experienced bloody spots in her underwear accompanied by dysuria. The mother brought her to the emergency department, where she was treated with antibiotics for a urinary tract infection.

Our physical examination revealed well-circumscribed, symmetric, depigmented, confluent, crinkled, parchment-like plaques with small hemorrhagic erosions on the medial labia majora and minora. The lesions had spread to the perianal area with depigmentation superiorly and hypopigmentation inferiorly, creating a figure-8 pattern.

A review of systems was negative for pruritus, pain, dysuria, dyschezia, constipation, and vaginal discharge. The patient denied sexual activity, depression, or anxiety. Her mother denied behavioral changes in her daughter and said that her daughter hadn’t had any one-on-one time alone with any adults besides herself. Her mother was concerned that the white spots might spread to the rest of her daughter’s body, which could affect her socially.
