Papulopustular rosacea and rosacea‐like demodicosis: two phenotypes of the same disease?

Background Papulopustular rosacea and rosacea‐like demodicosis have numerous similarities, but they are generally considered as two distinct entities, mainly because the causal role of the Demodex mite in the development of rosacea is not yet widely accepted. Several clinical characteristics are traditionally considered to differentiate the two conditions; for example, papulopustular rosacea is typically characterized by central facial papulopustules and persistent erythema, whereas small superficial papulopustules and follicular scales rather suggest rosacea‐like demodicosis. However, none of these characteristics is exclusive to either entity.
