Abstract

Hair follicle nevus is a rare benign follicular hamartoma that is characterized histologically by the proliferation of vellus hair follicles with peri-follicular fibrous thickening. Clinically, hair follicle nevus is most commonly reported as an asymptomatic papule or nodule on the head and neck. Here, we describe an unusual presentation of hair follicle nevus presenting as an atrophic plaque on the cheek of a male infant.

Keywords: congenital vellus hamartoma; follicular disorder; hair follicle nevus.
