Popis: Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft tissue neoplasm with low-intermediate grade of malignancy. It is a locally aggressive tumour with a high recurrence rate. Surgical excision with adequate margins is the main treatment.We describe the clinicopathological features of 21 cases of DFSP. The mean size of the lesions was 5.6 cm, mostly located in trunk. 61.9% of the cases underwent surgical excision without previous biopsy. 52.4% of the patients presented positive margins, that required surgical extension.The recurrence rate was 28.6% (6 cases), five of them local recurrences treated with new surgical excision with wide margins. Median period free of illness was 32.5 months. Medium follow-up period was 33.25 months.DFSP has a locally high recurrence rate, that has been associated to inadequate surgical margins. The histological knowledge preoperatively would permit surgical excision with adequate margins, and probably this could reduce the recurrence rate. Radiotherapy could avoid the surgical extension of margins in these cases with positive ones. Chemotherapy could be indicated in metastasic cases. Most recurrences appear in the first 3 years, but it is important a long-term follow-up of these patients.
