An unusual spiculated presentation of follicular porokeratosis

Year: 2019

Type: article

Abstract: Follicular porokeratosis is a rare variant of porokeratosis in which the coronoid lamellae are confined to hair follicles. It classically presents with annular plaques with a surrounding keratotic ridge. However, the clinical presentation has shown significant variation in reported cases. We present the case of a 26-year-old man with chronic diffuse follicular spicules associated with alopecia. Clinical findings were suggestive of trichodysplasia spinulosa, but multiple biopsies showed findings consistent with follicular porokeratosis. Diffusely spiculated presentation as present in our patient has not been previously reported in the literature. It is important to recognize the necessity of histopathologic confirmation in a diagnostically challenging condition such as follicular porokeratosis.
