History

Patient is a 52-year-old male with hip pain.

Findings

Intertrochanteric lytic lesion in the proximal femur with sclerotic rim and internal matrix calcifications.

Diagnosis

Liposclerosing myxofibrous tumor

Discussion

Liposclerosing myxofibrous tumor of the bone is a benign fibro-osseous lesion which is histologically characterized by a mixture of lipoma, fibroxanthoma, myxoma, myxofibroma, and fibrous dysplasia. This is often discovered incidentally and radiologically presents as a lytic lesion with sclerotic borders. The lesion may be expansile and is often seen in the femur. It is important to follow the lesion because there is possibility for malignant transformation.
