They cautioned that their research is not definitive but should provide strong evidence that PPR and rosacea-like demodicosis are the same disease.
“While our observations do not prove a causative role of Demodex in rosacea, they nevertheless support the idea that PPR and rosacea-like demodicosis should no longer be considered as two separate entities but, rather, as two phenotypes of the same disease,” they wrote. “As such, the definition of rosacea subtype II (PPR) should be reconsidered and simplified to include all patients with central face papulopustules – with or without persistent erythema – and thus also patients with ‘rosacea-like demodicosis,’ which is a term that should therefore disappear.”
