Common in males with mean age of 30-40 years. It can be discovered incidentally, but most patients have vague pain. 10% of patients may present with pathological fracture.
The tumor comprises of mixture of tissues of lipomatous, fibroxanthomatous, mxomatous and myxofibromatous components.
Malignant transformation to osteosarcoma is 10-15%, so the lesion needs follow up imaging preferably by MRI. symptomatic lesions or those with interval change require surgical resection.
Differential diagnosis:
Fibrous dysplasia, aneurysmal bone cyst, intra osseous lipoma.
