Liposclerosing myxofibrous tumor (LSMFT) is a fibro-osseous lesion of the bone with a marked predilection for the intertrochanteric region of the proximal femur. It is characterized by a complex mixture of histological elements including fibrous dysplasia-like features, myxofibrous tissue, lipomatous area, ischemic ossification, xanthoma cells and pseudo-Paget's bone. Though some consider LSMFT as a variant of the fibrous dysplasia, intraosseous lipoma, or other benign osseous lesions, recently LSMFT is emerged as a genuine clinicopathologic entity. We experienced a 48-year female patient with typical histologic and radiologic findings of LSMFT. It was located at the intertrochanteric area of the femur. Radiologically, the lesion was radiolucent and ground-glass appearance with sclerotic rim in the plain film and magnetic resonance imaging. Histologically, myxofibrous tissue, lipomatous area and fibrous dysplasia-like features were predominant findings.
