A Case of Metastatic Intracardiac Rhabdomyosarcoma Arising from Malignant Tumor in Other Site

ABSTRACT

A 29-year old woman was admitted to the hospital with dyspnea and chest pain. She had undergone a craniotomy due to anaplastic astrocytoma 4 months ago and mass excision of right calf and vagina 3 months ago. The histopathological findings of masses were embryonal rhabdomyosarcoma. Echocardiography showed a highly mobile elongated mass in left atrium and the mass protruded through the aortic valve during systole. Histopathological examination of the resected cardiac tumor showed cells of embryonal rhabdomyosarcoma.
