Benign fibrous histocytoma of femur: a case report

[摘要] Benign fibrous histocytoma (BFH) is a rare benign tumor, commonly occurs in soft tissues withvery few cases in bone recorded. BFH of bone usually occurs in patients after the age of 20 years and oftenlocates in the epiphysis or diaphysis of tubular bones, especially the femur and tibia. Herein we report acase of BFH of femur. The radiography and CT scan revealed a well-defined unilocular osteolytic lesionin the left proximal femur with marginal sclerosis. MRI showed that the lesion was isointense on T1WI,heterogeneous hyperintense on fat-saturated T2WI, with hypointense ring in circumference. Intralesionalcurettage was performed. At pathological examination, the tumor was consisted of spindle-shaped cells andscattered histocytic cells. The final diagnosis of BFH was established.
