Abstract
Benign fibrous histiocytoma (BFH) is a rare benign bone tumor. Its diagnosis is challenging considering the similarities in clinical symptoms, radiological characteristics, and histological features with other benign lesions. We present the case of a 56-year-old woman with BFH in the tibia. Radiograph demonstrated an osteolytic lesion with sclerotic rim at the epi-metaphysis of the left proximal tibia. Magnetic resonance imaging showed low signal intensity on T1-weighted images, heterogeneously high signal intensity with low signal in surrounding rims on T2-weighted images, and peripheral enhancement on T1-weighted images. Whole body bone scan showed a focal hot area at the left proximal tibia. The patient underwent tumor curettage and was diagnosed with BFH via pathological examination.
