Angiosarcoma around a knee arthroplasty. Report of a case and literature review.

The development of periprosthetic malignancy in proximity to an arthroplasty has been a matter of debate since it was first reported in 1978. We report a case of tibial angiosarcoma, an extremely rare malignancy, which developed in proximity to a primary knee arthroplasty performed ten years before. To our knowledge this is the second case ever described around a knee arthroplasty.
