| Popis: | Induction of follicular germinative structures above a dermatofibroma (DF) is a common finding. Rarely, induction of a trichoblastoma in a DF has been observed. Here, we report the case of a desmoplastic trichoepithelioma induced by a DF. The lesion with clinical and histological appearance of a DF situated on the left dorsal foot showed an associated adnexal proliferation that fulfilled histopathological criteria of desmoplastic trichoepithelioma. Immunohistochemistry (Ber-EP4, Bcl-2, CK17, CK20, CK7, EMA, and Ki67) helped to confirm the diagnosis and to exclude possible differential diagnoses. |
