Benign fibrous histiocytoma involving the ends of long bone

Abstract

Five bone tumors, previously labelled as benign fibrous histicytoma in our Bone Tumor registry were reviewed. All the cases were reexamined clinically, radiologically, and histologically. Ages of the patients ranged from 17 to 68 years and all tumors involved the epiphysis or epiphysiometaphysis of long tubular bones. A diagnosis of giant cell tumor was suggested from initial radiographs in all cases. Three cases proved to be giant cell tumors of bone after thorough examination of previous histological specimens. In the diagnosis of benign fibrous histocytoma of epiphyseal origin in adults, the possibility of giant cell tumor of bone should always be kept in mind, and painstaking histological examination is required.
