概要

論文の詳細を見る
Two case reports of primary cardiac sarcoma, which is uncommon, are presented. The first case, a 38-year-old male, complained of chest tightness. Chest roentgenograms showed enlargement of the cardiac shadow and left pleural effusion. Transthoracic echocardiography and chest magnetic resonance imaging showed a tumor in the right atrium, and pericardial effusion. The tumor involved the right atrial wall and interatrial septum, and was partially resected. Pathohistological examination revealed angiosarcoma. He died 1 month later. The second case, a 19-year-old male complained of dyspnea and orthopnea. Chest roentgenograms showed pulmonary congestion. Transthoracic echocardiography showed a large mobile mass in the left atrium. An emergency operation was performed and the tumor was totally resected. Pathohistological examination demonstrated leiomyosarcoma. The postoperative course was uneventful, but the tumor rapidly recurred. Second and third operations were performed at intervals of 2 months. After the third operation, he was treated with radiotherapy. Local recurrence was not found but multiple distant metastases were found 2 months after completion of radiation therapy.
