Abstract

Abstract Background Radiation-induced osteosarcomas are a recognized complication of radiation therapy. Owing to the fact that it is rare, publications on radiation-induced osteosarcoma of the skull base are limited to a small series and some case reports. Case presentation We describe a rare case of a patient with a skull base radiation-induced osteosarcoma treated 11 years before with ionizing radiation for an undifferentiated carcinoma of the nasopharynx. The patient was treated with chemotherapy alone, but he died after the third cycle. Conclusions Radiation-induced osteosarcoma of the skull base after treatment of nasopharyngeal carcinoma is a very rare but very aggressive complication with a poor prognosis. Chemotherapy gives bad results, and regular follow-up of treated patients should be considered.
