Dermatofibrosarcoma protuberans - a rare, slow growing benign, locally agressive dermal sarcoma: A case report

Dermatofibrosarcoma Protuberans (DFSP) has been described as the most common dermal sarcoma. It is a rare, slow growing, low-grade malignancy that is locally aggressive and has a high rate of recurrence and low metastatic potential. Most DFSPoccur on the torso, proximal extremities, head and neck regions. DFSP is characterised by local aggressiveness and if not completely removed, it recurs easily. We report a case which presented with a 1x0.5 cm mass arising from the left upperposterior part of humerus. We referred the patient to a reconstructive surgeon after we conducted a detailed history and physical examination. After excisional biopsy, the histopathological studies revealed the lesion to be DFSP. This rare lesion can be neglected or thought tobe nevus or lipoma,especially by primary care physicians who play a very important role in the prevention and early diagnosis of precancerous lesions.
