Zosteriform eruptive vellus hair cyst: A rare entity with an uncommon presentation

Abstract

Eruptive vellus hair cyst (EVHC) represents a rare developmental anomaly of vellus hair follicles. The infrequency with which it is encountered makes it a formidable diagnostic challenge. Herein, we report a case of zosteriform EVHC in a 23-year-old male who presented to our dermatology clinic with asymptomatic, brown-black colored, follicular papules for 15 years. This case highlights a unique presentation of an uncommon entity.
