Folliculo-sebaceous hamartomas comprise a series of entities whose boundaries are imprecise. We present the clinical case of a folliculo-sebaceous cystic hamartoma of genital localization where the diagnosis was established based on the epithelial proliferation, but mostly, on the characteristic stroma. Because this lesion lacked of the cystic component, we mention the most frequent differential diagnoses and review the literature of the few cases published on this infrequent localization.

Folliculosebaceous cystic hamartoma (FCH) is a relatively rare and recently described lesion of the skin. Mostly, it involves the skin of the head and neck area. It is considered by most authors as a form of non-neoplastic cutaneous hamartoma comprising follicular, sebaceous and stromal elements. However, few regard it as a sebaceous trichofolliculoma, i.e. a variant of trichofolliculoma. FCH of the nipple of female breast is a very rare lesion with only one previous case reported so far in the literature. We report a similar case with a brief review of the literature.
