Clear-cell atypical fibroxanthoma: An unusual case in an unusual place.

Atypical fibroxanthoma represents a low-grade sarcoma that usually presents in the elderly population on sun-damaged areas of the head and neck regions. This neoplasm is characterized on histology by atypical pleomorphic, epithelioid to spindled cells, arranged in a haphazard pattern, set within a background of solar elastosis. In this case report, we present a unique case of the rare variant of clear-cell atypical fibroxanthoma arising in an unusual place, specifically the lower extremities.
