Lipomas are among the most common soft-tissue tumors, but they are rarely intra-osseous. Dahlin stated that a diagnosis of intra-osseous lipoma is made in about one out of every 1,000 bone tumors. In an excellent review of this tumor published in 1973, Hart found twenty-eight cases in the world literature. Since that time four more of these tumors, all involving the calcaneus, have been reported. This foci concerns an intra-osseous lipoma of the proximal end of the The first reported intra-osseous lipoma was described by Brault and was in the distal end of the femur. In 1965, Gennari and Bozzetti reported a second case in the distal end of the femur; Dahlin reported a third case in the femoral neck in 1967. No other cases have been reported in the femur.
