Epithelioid sarcoma, first described by Enzinger at 1970, is s malignant tumor of unknown origin and occur almost exclusively in the extremities, usually in the hand or foot associated with aponeurotic structure. These tumors differ in their natural history from most other sarcomas in that they have a greater tendency to spread to noncontiguous areas of skin, subcutaneous tissue, fat and bone. Its pathologic features are likely to be confused with chronic inflammatory process, a necrotizing granuloma, & squamous cell carcinoma. This tumor occurs chiefly in young male and grouws slowly but frequent recurrence and metatstasis to lungs are common. A 29 years old man was admitted to Chung-Ang University Hospital on August 26th, 1991, complaining with dyspnea and chest pain. He has been diagnosed as epithelioid sarcoma at left forearm 2 years ago. On chest X-ray and CT, multiple metastatic nodules were observed at right upper and middle lung fields with right pleural thickenning. Biopay of the protruded mass at right thoracic wall showed metastatic epithelioid sarcoma cells. In this paper, we report one case of recurrent epithelioid sarcoma with metastasis to lung and skin after radical operation.
