Liposclerosing myxofibrous tumor: a rare tumor of proximal femur.

Abstract

Liposclerosing myxofibrous tumor is a very rarely observed benign fibro-osseous lesion, which contains complex histological structures. It was first described in the year 1986. Histopathological examination of the lesion may show myxoid areas, osteoclastic activity, bone trabeculae similar to fibrous dysplasia, fat necrosis, ischemic ossification and rarely cartilage components. This lesion, which is particularly localized to the proximal femur, is thought to be associated with fibrous dysplasia. In this case report, we aim to present a liposclerosing myxofibrous tumor case, which was treated surgically, in light of the literature review. The patient who was treated with curettage, grafting and 95-degree dynamic condylar screw-plate system was asymptomatic at the 16th month control and recurrence was not detected.
