Dermatofibrosarcoma protuberans is a tumor of intermediate malignancy characterized by its aggressive local growth and marked propensity to recur after surgical excision. Many forms of the tumor has been reported. We report a pedunculated form of tumor. A 45-year-old woman felt a growing tumor on her trunk for 6 years but did not seek medical consultation until it had ulcerated 6 months ago. Skin biopsy confirmed the diagnosis of dermatofibrosarcoma protuberans. Radiological and sonographical examination failed to reveal any metastatic lesion.
