Malignant fibrous histiocytoma as a primary cardiac tumor.

We describe the case of a malignant fibrous histiocytoma (MFH) of the heart, presenting with an obstinate cough and clinically misdiagnosed as myxoma, in an 80-year-old woman. Fourteen months after surgical removal, an embolic episode revealed recurrence of the tumor. To plan the best surgical management, MFH, rare as it is, should be borne in mind when evaluating a cardiac intracavitary mass, especially if located in the left atrium.
