Radiation-induced osteosarcoma in the head and neak region is very rare. A 68-year-old female, who had been treated with radiation for malignant lymphoma of the right maxillary sinus, presented with right cheek swelling. Imaging examinations demonstrated a huge mass occupying the right nasal cavity and paranasal sinuses. Total maxillectomy was performed, and the tumor was histologically diagnosed as osteosarcoma. Diagnosis and treatment for radiation-induced osteosarcoma in the head and neck is discussed.
Key words : osteosarcoma, maxilla, radiation-induced carcinoma
