Liposclerosing myxofibrous tumour

Liposclerosing myxofibrous tumours are large conspicuous lesions, often discovered incidently on plain films or bone scans, with a predilection for the proximal femur. Radiographs typically show a geographic lytic lesion with a well-defined, often densely sclerotic margin. These lesions are characterized by a peculiar complex mixture of histological patterns individually typical of several well-described lesions. Rarely these lesions may undergo sarcomatous change.
