The Bednar tumor (BT) is a rare variant of dermatofibrosarcoma protuberans (DFSP) with melanin pigment in cells histologically.


A slow growing nodule, mass, or firm plaque on the trunk is typical. Metastases can occur, but rarely.


Mohs micrographic surgery is the treatment of choice. See dermatofibrosarcoma protuberans.
