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.
