We presented a case of a patient seventy and four
years old with a painful left hip during the last 12 months. On
the x-ray exploration, appear a quistic lesion, localizated on
the proximal femur and with arthrosis signs of the coxofemoral
joint. We indicated a total hip arthroplasty, cemented, during
the surgery the lesion is legrated, and the histologic study
reveal a intraosseus lipoma, without maling signs. At two years,
the patient is asintomatic, and no indicius of the femoral
tumor. We presented this case, the intraosseus lipoma, making
the diferential diagnosis and revised the bibliografy of
this rare osseous tumor.
