Abstract
- Folliculosebaceous cystic hamartoma is a rare cutaneous hamartoma comprising follicular, sebaceous, and mesenchymal elements. This tumor usually presents during adulthood as an exophytic papule or nodule on the scalp or central area of the face. Histopathologic features are central cystic structures lined with infundibular epithelium, numerous sebaceous gland lobules radiating from cystic structures, and surrounding stroma composed of fibrillary bundles of collagen, small vessels, neural tissue and occasionally mucin deposits. We herein report a case of folliculosebaceous cystic hamartoma in a 21-year-old man who presented with a skin-colored, dome-shaped papule on the scalp.
