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.
我们报告了一例25岁女性因左髋部疼痛就诊的病例。在股骨近端干骺端发现一个病灶。基于普通X线片和磁共振成像，怀疑为良性骨肿瘤，如骨内脂肪瘤或脂肪硬化性黏液纤维瘤。对病灶进行了刮除和植骨。组织学检查结果显示为股骨近端原发性骨内黄瘤。实验室检查显示患者血脂正常，而脂蛋白免疫电泳分离显示α、前β、β和乳糜微粒值正常。在一年的随访中，没有局部复发的迹象。这是首例血脂正常患者的股骨近端原发性骨内黄瘤报告病例。
