<unk>  (LSMFT) of bone, a benign fibro-osseous lesion, is characterized by a complex mixture of histologic elements. These include lipoma, fibroxanthoma, myxoma, myxofibroma, fibrous dysplasia –like features, cyst formation, fat necrosis, ischemic ossification, and, rarely, cartilage. LSMFT has a striking predilection for the femur (approximately 85% of the lesions). Approximately 91% of the femoral lesions are in the intertrochanteric region. The prevalence of malignant transformation in LSMFT has been reported to be 10%–16%. The increased propensity of LSMFT for malignant transformation is likely to be secondary to its extensive involutional and ischemic change, with the associated sarcoma arising from areas of ischemic ossification within the lesion or from progressive in situ atypism of the altered lipomatous elements.
