Abstract

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumor with a high incidence of misdiagnosis. DFSP has a high rate of recurrence but a low rate of metastasis. In the present study, retrospective analyses were performed on the clinical features, differential diagnosis and treatment of patients with DFSP to improve our understanding of the disease and allow more effective treatment measures to be implemented. The present study investigated the clinicopathological features of 70 pathologically confirmed cases of DFSP at the First Affiliated Hospital of Zhengzhou University (Zhengzhou, China) between March 2012 and 2017. The primary endpoint was recurrence rate. Three cases were analyzed in detail. The results revealed that 7 of the 41 primary patients (follow‑up at 2.7 years) had recurrence (17.1%), compared with 11 (37.9%) of the 29 recurrent patients (follow‑up at 2.0 years, P=0.049). Of the 59 patients with DFSP (follow‑up at 2.6 years), 12 had recurrence (20.3%) compared with 6 (54.6%) of the 11 patients with fibrosarcomatous DFSP (FS‑DFSP; follow‑up at 2.1 years, P=0.045). DFSP requires diagnosis by pathological examination, and surgical resection is the main treatment. DFSP demonstrated a high recurrence rate, with the degree of malignancy increasing following multiple recurrences. FS‑DFSP had a higher risk of local recurrence and distant metastasis, and a higher degree of malignancy than classic DFSP. These data may be useful to guide clinicians to improve decisions in the treatment of patients with DFSP.
