Epithelioid sarcoma with retained INI1 expression as a cause of a chronic leg ulcer.

Epithelioid sarcoma is a rare soft-tissue sarcoma typically presenting itself as a subcutaneous or deep dermal mass in distal portions of the extremities of adolescents and young adults. They are frequently mistaken for ulcers, abscesses, or infected warts resistant to standard medical treatment. Patients often develop multiple local recurrences with subsequent metastases. We report a case of a 66-year-old patient with chronic leg ulcer who died of generalization of an epithelioid sarcoma.
