[Dermatofibrosarcoma protuberans about 18 cases]

ABSTRACT

Dermatofibrosarcoma protuberans [DFSP] is a rare mesenchyma skin tumor. It is characterized by a slow growth with a high rate of recurrence but limited potential for metastasis. We report the result of a retrospective study of 18 cases of DFSP collected over 16 years in the dermatology department of La Rabta Hospital. The mean age was 32 years with a sex ratio of 1.57. The site of predilection was the trunk [77.5%]. Histological features were typical in all cases with positivity for CD34 in 14 cases. Treatment was surgical in 13 cases. DFSP is a tumor of intermediate malignancy, which can have aggressive course. This tumor is best treated with surgery in which large excision are necessary to reduce the risk of recurrence
