Primary malignant cardiac tumors are extremely rare. Among these, leiomyosarcoma are particularly exceptional and only about 20 surgically treated cases have been extensively described. We describe a case of right atrial leiomyosarcoma which was accidentally found by computed tomography. The tumor was surgically resected under extracorporeal circulation. Two months later the patient had cerebral hemorrhage due to a brain metastasis, which almost completely disappeared after irradiation. There was no other evidence of recurrence for 12 months after operation.
