Liposclerosing Myxofibrous Tumor in a Patient with Prostate Cancer: A Case Report.

CASE: A 64-year-old man diagnosed with prostate cancer was incidentally found to have a lesion in his distal femur. Although initially concerning for metastatic prostate cancer, after biopsy by an orthopaedic oncology specialist, a diagnosis of liposclerosing myxofibrous tumor (LSMFT) was confirmed. The lesion was treated with curettage and demineralized bone matrix grafting with close follow-up.

CONCLUSIONS

This case report illustrates that LSMFT is not confined to the proximal femur and highlights the differences in radiographic appearance between LSMFT and more common metastatic bone lesions.
