[Radiological characteristics of malignant fibrous histiocytoma of bone].

Malignant fibrous histiocytoma (MFH) was only recognized as a primary bone tumor a few years ago. Although it is much rarer than malignant fibrous histiocytoma of soft tissues, it is not extremely uncommon. It predominantly affects long bones; however, it has been reported to occur in many different sites and at any age. MFH are aggressive tumors that can appear in association with other bone lesions, and they have a poor prognosis. We present our experience with 13 cases of MFH and review the literature to describe the main characteristics of this tumor.
