A Case of Dermatofibrosarcoma Protuberans with Myxoid Area

ABSTRACT

Dermatofibrosarcoma protuberans is a rare, slowly growing, locally invasive spindle-cell tumor characterized by a protuberant cutaneous mass with a pronounced tendency to recur and by a prominent storiform histopathologic pattern'-'. We present a case of dermatofibrosarcoma protuberans with myxoid area on the chest of a 57-year-old man. The histopathological study showed a dermal tumor of uniform spindle-shaped cells with storiform pattern. Immunohistochemically, the tumor was stained positively to anti-CD34 antibody and negatively to anti-factor XIIIa antibody.
