Hemangioendothelioma of the leg following metallic fixation of the tibia

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.
