 The study analyzed the clinical pathologic factors and treatment outcomes of 80 patients with dermatofibrosarcoma protuberance, DFSP, treated between 2007 and 2017 in Shanghai 9th People's Hospital. The results showed that wide margin excision with margins over 3 centimeters had a lower recurrence rate compared to local excision, while Moh's surgery was effective in preventing recurrence. Transformed DFSP had a greater tendency to recur. Therefore, achieving clean margins of excision and using slow Moh's surgery is recommended for treating DFSP.
