Hemangioendothelioma of the leg following metallic fixation of the tibia

Authors


Abstract

A hemargioendothelioma involving the tibia and the soft tissues of the leg developed at the site of a metal plate implanted for non-union of a fracture. The plate had been retained for 30 years. Metallurgical examination identified the plate and six screws as a type 316 stainless steel as compared to two screws which were composed of type 304 stainless steel. The use of dissimilar metals as surgical implants may have been a contributing factor for the corrosive attack demonstrated at two type 304 screws and two screw holes in the plate and pick-up of metals by the tissue. The possibility was considered that the metallic corrosion products triggered the formation of the hemangioendo-thelioma.
