title: Dermatofibrosarcoma protuberans: a case report and clinicopathologic review.
abstract: Dermatofibrosarcoma protuberans is a soft tissue, low-grade malignant tumor. Histologically, the tumor is a low-grade sarcoma with a constant storiform growth pattern. The tumor may possibly arise from histiocytes, a thesis supported by recent tissue culture and electron microscopic studies. Treatment consists of the wide local excision. Conservative excision often results in recurrences. Lymph node and other distant metastases, although rare, have been documented. Most often, the clinical course shows this tumor to be slow growing and often painless. Presented herein is a patient in whom this uncommon tumor developed.
