Metastatic synovial sarcoma of the left ventricle.
A metastatic synovial sarcoma of the left ventricle is described. A 26-year-old Japanese woman underwent resection of a synovial sarcoma of the right thigh 8 years prior to admission, which was followed by multiple surgical procedures for pulmonary metastasectomy. Echocardiography demonstrated obstruction of the outflow tract of the left ventricle caused by a metastatic tumor, which was surgically resected on the day of admission. The histologic characteristics of the cardiac tumor were identical to those of the pulmonary metastases. Additional cardiac metastasectomy was performed 9 months later. She complained of dyspnea on exertion 8 months after the second cardiac metastasectomy due to recurrence in the heart. Radiotherapy with LINAC (a total dose: 50 Gy) diminished the size of the tumor temporarily. The patient died 20 months after the initial cardiac metastasectomy.
