Primary liposarcoma is one of the common soft tissue neoplasms, occurring most commonly in the lower extremities and retroperitoneum. Primary mediastinal liposarcoma is rare. In our review of the literature in Japan we found 44 reported cases. We treated a patient with primary mediastinal liposarcoma which was diagnosed histologically as myxoid type. A-58-year-old male was admitted to our hospital for further investigation and treatment of a tumor in the left upper mediastinum. Chest CT scans demonstrated a non-enhanced mass with water density in the anterior mediastinum. Resection of the tumor was performed successfully. The pathological diagnosis was myxoid liposarcoma. The patient had no additional therapy and is free of disease one year after operation. Extended surgical removal is recommended treatment, so far. The survival of patients with mediastinal liposarcoma depends on its histologic type, location, and the adequacy of surgical removal.
