Monostotic Fibrous Dysplasia of the Proximal Femur and Liposclerosing Myxofibrous Tumor: Which One Is Which?

The article presents the clinical, histological, and genetic studies of two cases of isolated fibro-osseous lesions of the femur in adults. It shows the overlap between monostotic fibrous dysplasia (MFD) of the proximal femur and the liposclerosin myxofibrous tumor. The two cases highlight how the incomplete understanding of the natural history of MFD may result in diagnostic pitfalls or incorrect classification of individual lesions.
