Sebaceoma. A distinctive benign neoplasm of adnexal epithelium differentiating toward sebaceous cells.

Sebaceoma is a new term proposed to designate a distinctive benign neoplasm of adnexal epithelium with differentiation toward sebaceous cells. Clinicopathologic correlation of the condition is presented in a study of 14 cases. This neoplasm has many histologic features in common with trichoepithelioma and cylindroma, both of which are benign neoplasms of adnexal epithelium, one with follicle-like and the other with eccrine-like differentiation. Sebaceoma is a recently recognized entity, and the term is recommended to supersede, not merely to redefine, what has been previously called sebaceous epithelioma.
