Angiosarcoma around a revision total hip arthroplasty and review of literature.

Development of cancer in association with metallic implants is well recognized yet poorly understood. We report a case of angiosarcoma at the site of a revision total hip arthroplasty. We found only 3 previous reports on angiosarcoma associated with hip arthroplasty in English literature. Association between malignant tumor and hip arthroplasty deserves attention because this surgical procedure is so common that possible risk of a neoplasm should be quantified. Sarcoma is rare, and its possible causation by retained foreign body material has been reported only as single cases.
