A patient with an apparently benign lesion of the distal femur presented at our Outpatient Department. Pain was the chief complaint. There were histological features of Non-ossifying Fibroma in the lesion. Because of its unusual radiological appearance and atypical clinical course, the lesion was diagnosed as Fibrous Histiocytoma.
