Traumatic anserine folliculosis (TAF) is an under-recognized and under-reported entity that is commonly mistaken as comedonal acne. It is seen in children and young adults and friction has been implicated as a probable factor in its causation. As face is the commonest site, biopsy may not be a feasible diagnostic option. Dermoscopy proves to be a reliable non-invasive diagnostic tool to differentiate these two disorders. In this article, we describe the dermoscopic features of TAF in three patients and also attempt to highlight the clinical and dermoscopic distinction between TAF and comedonal acne.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
