초록
We report the case of a 25-year-old woman presenting with left hip pain. A lesion was found in the proximal femoral metaphysis. Benign bone tumor, such as intraosseous lipoma or liposclerosing myxofibrous tumor, was suspected based on simple radiographs and magnetic resonance images. Curettage of the lesion and bone grafting was performed. Histologic findings reflected primary intraosseous xanthoma of the proximal femur. Laboratory tests revealed the patient to be normolipidemic, while immunoelectrophoretic fractionation of lipoproteins revealed normal values for alpha, pre-beta, beta, and chylomicrons. At the one-year follow-up, there was no evidence of local recurrence. This is the first reported case of primary intraosseous xanthoma of the proximal femur in a normolipidemic patient.
