We report a rare case of cardiac metastases of leiomyosarcoma. A 64-year-old woman presented with chest pain. Nineteen years ago, she had undergone resection of uterine leiomyosarcoma 19 years pveviously and 9 years previously, resecting of colon metastases. Echocardiogram and computed tomogram revealed tumor in the right ventricular outflow tract, which moved into the pulmonary artery. Because obstruction of the main pulmonary artery was possible, the tumor was resected. The tumor was leiomyosarcoma, which suggested metastasis from the uterine tumor. No recurrence of the tumor was seen 9 months after surgery despite lack of any treatment.
