[A case report of primary cardiac leiomyosarcoma].
A 26-year-old woman presenting symptoms of rapid progressive heart failure consulted with our hospital. Two-dimensional echocardiography showed a large mass in the left atrium (LA) and severe pulmonary hypertension. Emergent operation was performed because of hemodynamic reason and the risk of embolism. The tumor (7 x 6 x 3 cm) which was lobulated and had a smooth surface was arising from posterior wall of LA extending into the ostium of right lower pulmonary vein. The portion of tumor located was excised. The defect was reconstructed by bovine pericardium. Postoperative histopathological diagnosis was leiomyosarcoma. Hemodynamics recovered after surgical treatment and there were no problems for 5 months. However, tumor recurrence in LA and pulmonary metastasis was found 5.5 months after surgery. The patient died two weeks later by progressive heart failure. Primary cardiac leiomyosarcoma is extremely rare. The current world literature is reviewed with respect to this rare tumor.
