Iatrogenic implantation of myxoid dedifferentiated chondrosarcoma at donor site: A case report and review of literature

Iatrogenic implantation of chondrosarcoma (CS) is not only extremely rare but also technically avoidable and impacts with morbidity, mortality, and quality of life (QoL). We report a similar case of myxoid dedifferentiated CS at remote tissue-graft donor site (left chest-wall pectoralis major myocutaneous flap). Although the exact mechanism of primary tumor cells seeding is not clear, the probable causes are direct contamination from surgical instruments and altered blood circulation at the graft-donor site.
