Malignant fibrous histiocytoma of the female breast: A case report

Malignant fibrous histiocytoma (MFH) of the breast is very rare. Sonographic findings of MFH of the breast have not been reported before. We herein report a case of a 46-year-old woman with a histologically proved MFH of her right breast. Ultrasound examination revealed a 6-cm tumor mass with solid and cystic components, which were attributed after histological examination to hypercellularity and hemorrhage within the tumor. Histopathological diagnosis was compatible with MFH of the breast.
