title: Combined adnexal tumor of the skin.
abstract: Two patients had distinctive adnexal skin tumors that showed cellular differentiation toward the formation of more than one adnexal structure. In one patient, the tumor showed differentiation toward pilar and sweat ductal structures. In the second patient, tumor differentiation toward the formation of sebaceous glands, pilar, and sweat ductal structures was found. We propose the term "combined adnexal tumor of the skin" for this neoplasm.
