Malignant fibrous histiocytoma of bone

Malignant fibrous histiotoma (MFH) mostly occurs in deep soft tissues. It was first reported by Orsquo; Briea and Stoat, and it is rare in primary bone. In 1972, Feldman and Norman proposed this tumor as an independent type of bone tumor. Previously, MFH was often mistaken for osteosarcoma, fibrosarcoma, giant cell tumor of bone, or bone metastatic cancer.
