title: Malignant fibrous histiocytoma at site of metal implant.
abstract: The occurrence of malignant tumors at the site of metal implants is rare. The significance of this association is not settled. Its implications, however, are serious. A malignant fibrous histiocytoma arising at the site of an implant done 14 years ago for traumatic fracture of the femur in a 44-year-old man is reported. Previous reports are briefly summarized.
