Dermatofibrosarcoma protuberance: case reports

Dermatofibrosarcoma protuberance (DFSP) is a relatively uncommon soft tissue neoplasm with intermediate to low grade malignancy, rarely metastasizing to regional lymph node or distant site but with proclivity for local recurrence due to inadequate resection. We evaluated the clinical histories and treatment outcomes of five consecutive patients who had histologic diagnosis of DFSP in the University of Calabar Teaching Hospital between 2000 and 2004. The five cases reported had histologic diagnosis, sought for after excision. The male:female ratio was 2:3 with an age range of 17-35 years (mean, 26.6 years). Two of the lesions involved the neck and the other three sites involved were the anterior chest wall, groin and proximal thigh. Three of the lesions were recurrent. DFSP is an uncommon tumour, painless, cutaneous and multilobulated lesions should arouse the suspicion of this tumour. Early presentation, pre-operative histologic diagnosis and postoperative evaluation of resection margins would enhance the goal of ensuring adequate excision for improved outcome.
