Primary cardiac leiomyosarcomas are very rare. A 19-year-old man was admitted to a local hospital with dyspnea and hemoptysis. He was later transferred to our hospital because of his worsening dyspnea. An enhanced chest computed tomography scan demonstrated a large mass in the left atrium. A transthoracic echocardiogram showed a large mobile mass in the left atrium. The tumor was totally resected. The pathohistological examination showed leiomyosarcoma. The tumor rapidly recurred. and a second and third operation were performed. After the third operation, the patient was treated with radiotherapy. There was no local recurrence but multiple distant metastases were found 2 months after completion of radiation therapy.
原发性心脏平滑肌肉瘤非常罕见。一名19岁男性因呼吸困难和咯血入住当地医院。后来由于呼吸困难加重被转至我院。胸部增强计算机断层扫描显示左心房有一个大肿块。经胸超声心动图显示左心房有一个大的活动肿块。肿瘤被完全切除。病理组织学检查显示为平滑肌肉瘤。肿瘤迅速复发，进行了第二次和第三次手术。第三次手术后，患者接受了放射治疗。放疗结束2个月后，未见局部复发，但发现多处远处转移。
