title: Synovial sarcoma of the mediastinum: report of a case.
abstract: We report a case of synovial sarcoma of the mediastinum, a very rare tumor, in a 50-year-old man hospitalized with anterior chest pain. Chest X-ray and computed tomography (CT) on admission showed a 10 x 8-cm mass in the right anterior mediastinal space, compressing the superior vena cava. A diagnosis of sarcoma was established by a CT-guided percutaneous needle biopsy. Systemic examination revealed no metastasis to the contralateral pleural cavity or other distant organs, and we resected the mediastinal sarcoma. Pathological and immunohistochemical analyses confirmed a diagnosis of monophasic synovial sarcoma. The patient is alive with recurrence 9 months after his operation, and is receiving chemotherapy with ifosfamide.
