Intraosseous lipoma is one of the rarest primary benign tumors of bone and it is characterised by a neoplastic overgrowth of univacuolar fat cells. The incidence is less than one per 1,000 bone tumors. Most commonly, long bones are affected, with a tendency for metaphyseal involvement. Because of its rarity and nonspecific clinicopathologic findings, biopsy is needed for accurate diagnosis. Currettage and bone-grafting is the treatment of choice if the lesion is painful or if structural stability is threatened. We report 3 cases of intraosseous lipoma in long tubular bones with review of literatures. Two cases were treated by surgical intervention and the other case by conservative management.
