Dermoscopy of Anserine Folliculosis

摘要

Anserine folliculosis is a rare dermatological entity presenting with multiple closely grouped follicular-oriented papules on the chin, neck, and jaw. It is difficult to clinically differentiate it from other folliculocentric keratotic disorders like keratosis pilaris, lichen nitidus, follicular mucinosis, and folliculotropic mycosis fungoides (FMF). Dermoscopy can provide an essential clue in the diagnosis of anserine folliculosis and differentiate it from other known entities.
