Abstract

Folliculosebaceous cystic hamartoma is a rare cutaneous hamartoma comprised of follicular, sebaceous, and mesenchymal elements. It usually presents as an exophytic papule or nodule on the central part of the face. The histological findings are intradermal cystic structures lined by infundibular epithelium, numerous sebaceous lobules radiating from cystic structures and a surrounding stroma composed of mesenchymal changes, including variable proportions of fibrous, adipose, vascular and neural tissues. We herein report a case of folliculosebaceous cystic hamartoma in a 73-year-old man who presented with a skin-colored, dome-shaped papule on the right nasal ala.
