title: [Bone liposclerosing myxofibrous tumor. Case presentation and literature review].
abstract: The bone liposclerosing myxofibrous tumor (LSMFT) was initially described by Ragsdale in 1986 as a polymorphic fibroosseous bone lesion with a mix of histologic elements that include lipoma, fibroxanthoma, myxoma, myxofibroma, fat necrosis, ischemic ossification, areas of fibrous dysplasia, and infrequent presence of cartilage or cystic changes. The most frequently reported location is the intertrochanteric area of the femur. Radiologically it is a lytic, geographic lesion, with well-defined margins and usually sclerotic. In some cases findings include mineralization inside the lesion or a certain degree of expansion to the contour. The close relationship between LSMFT and fibrous dysplasia has been described based on the histologic characteristics and the presence of the Gsα mutation. Another hypothesis of the etiology of the lesion is the reaction of fibrous dysplasia to stress.
