Dermatofibrosarcoma protuberans (DFSP) is a slow-growing cutaneous spindle-cell tumor of intermediate to low-grade malignancy, typically arises in the dermis and subsequently infiltrates the subcutaneous tissue. It usually begins as a red-brown indurated plaque, and develops into nodules slowly over many years. Atrophic DFSP is a rare variant of DFSP, which presents as a depressed violaceous scar-like lesion with atrophic patch. The biologic behavior and histologic characteristics of atrophic DFSP is identical to classical DFSP. However, atrophic lesion is difficult to diagnose clinically as DFSP. A 54-year-old female presented with a 1-year history of an asymptomatic erythematous to violaceous atrophic patch on her upper trunk. There was no history of trauma in the vicinity of the lesion. Punch biopsy showed densely packed, monomorphous, plump spindle cells arranged in a storiform pattern, infiltrating the dermis and subcutaneous tissue, producing a honeycomb pattern. Immunohistochemical study showed diffuse and strong positivity with CD34, negativity with S-100 protein. The diagnosis of atrophic DFSP was made based on clinical, histological features and immunohistochemical stain. The patient was referred to the department of plastic surgery for wide excision. We herein report unusual clinical features of DFSP presenting as an atrophic, telangiectatic patch with review of literature.
