MALIGNANT FIBROUS HISTIOCYTOMA OF THE HEART

Abstract
A 33 yr old woman presented signs and symptoms which suggested mitral stenosis and insufficiency. Subsequent echocardiographic and angiographic testing demonstrated a left atrial tumor which was suspected clinically to be a left atrial myxoma. At surgery, the tumor was partially resected and histological examination revealed the mass to be a malignant fibrous histiocytoma. At autopsy, the tumor was localized in the heart and there was no metastasis.
