Malignant Fibrous Histiocytoma In The Heart; An Autopsy Case

Malignant fibrous histiocytoma (MFH) in the heart is rare. At autopsy, MFH of the left atrium was diagnosed in a 36 year old woman. The mass involved the left left ventricular wall. Histopathologic examination revealed that the tumor consisted of malignant cells with marked atypia. Immunohistochemistry showed a diffuse immunoreaction for vimentin. The histopathologic diagnosis was MFH. We present a case of a 36-year-old woman with histologically confirmed MFH in the left atrium.
