Abstract

Nevus sebaceus is a congenital hamartoma with epidermal, follicular, and apocrine elements. Several skin appendage tumors can evolve secondarily from nevus sebaceus. Two different tumors often develop simultaneously on a nevus sebaceus lesion, but the growth of more than two tumors is rare. Herein, we report a case of four appendage tumors including trichoblastoma, tumor of the follicular infundibulum, sebaceoma, and sebaceous hyperplasia within a single nevus sebaceus lesion on the face of a 76-year-old female.
