Olfactory neuroblastoma (ONB) is a rare, malignant tumor of the olfactory epithelium. Especially, radiation induced ONB is extremely rare and only 4 cases were published. We present a case of ONB that occurred after concurrent chemo radiotherapies of undifferentiated carcinoma then treated with surgical resection and combination chemotherapy. And we reviewed the 5 cases of radiation induced ONB including this case. Radiation therapy is increasing in the large percentage of the oncology population. So close observation and suspicion of second primary malignancy including ONB is necessary.
