Radiation-induced osteosarcomas (RIOS) after nasopharyngeal carcinomas are rare complication of radiotherapy and are associated with poor prognosis. Few cases are reported in the literature. Case report: We report a case of radiation-induced osteosarcoma involving the proximal humerus in a patient treated with radiotherapy for nasopharyngeal carcinoma (NPC) nine years ago. Surgical treatment could not be performed, and the patient received induction chemotherapy. He died from disease spread after three cycles. Conclusion: RIOS after treatment of NPC is very aggressive complication. Only a regular follow up of treated patient allow early detection of these tumors and best chances of survival.
