Iatrogenic implantation of giant cell tumor at bone graft donor site and clinical recommendations to prevent "a rare avoidable complication".

Abstract

The treatment of giant cell tumor of bone is directed toward local control without sacrificing joint function. This is achieved by intralesional curettage. When autograft is used for the reconstruction of the curetted cavity, there is always a theoretical risk of contamination of graft donor site. We report a case of iatrogenic implantation of giant cell tumor at the bone graft donor site after intralesional curettage and bone grafting of giant cell tumor of distal femur. Patient was treated with repeat intralesional curettage and excision of implantation lesion at bone graft donor site. We recommend precautionary measures to prevent this avoidable complication.
