Abstract
The incidence of radiation-induced tumors is increasing in the oncology population as a result of increased survival, with
improvement in cancer treatment. Exposure to therapeutic doses of radiation has also been shown to be associated with an
increased risk of a second cancer, though the precise risk remains unknown. The occurrence of sarcomas in irradiated tissues is
an uncommon but well-documented long-term complication of radiotherapy. In the current study, the case of a 55-year-old man
presented with maxillary osteosarcoma occurring 22 years post radiation for his maxillary lymphoma.
