Surgical treatment of dermatofibrosarcoma protuberans. A retrospective study of 20 cases with review of literature.
The clinicopathological features and results of surgical treatment of 20 patients with dermatofibrosarcoma protuberans (DFSP) were reviewed. All patients have been observed until the present time or death. The primary treatment usually consisted of marginal, wide or radical excision. Re-excision because of recurrence was performed in six of the 20 patients who were treated primarily only by marginal excision. Following re-excision two patients have remained disease-free until the present, the other four of these six patients had a second recurrence. Three of these four patients with a second relapse were successfully treated by excision. Although six patients out of 20 had 13 recurrences at the site of primary therapy, no patient developed lymph node or distant metastases. To date, none of the remaining 14 patients has had recurrence, all having been treated by excision of from 1 to 5 cm, the mean follow-up time was 8.75 years. Based on our data, the high recurrence rate after marginal surgical treatment implies an initial radical resection.
