A Case of Trichoblastoma with Trichoepithelioma-like and Sebaceous Differentiation / 대한피부과학회지

ABSTRACT

We report a 40-year-old woman with trichoblastoma on vertex scalp showing trichoepithelioma-like feature in upper part and focal sebaceous differentiation. The co-presence of trichoblastoma and trichoepithelioma-like feature in a same tumor represented that the inclusive term trichoblastoma is better for trichogenic tumors composed of follicular germinative cells, and sebaceous differentiation meant the common embryonic origin of folliculo-sebaceous-apocrine unit.
