A case of olfactory neuroblastoma is reported. A 74-year-old man visited our hospital exhibiting left nasal obstruction and bleeding in May 1997. An examination revealed a large tumor in his left nasal cavity; its surface was smooth and it bled easily. The patient did not have any visual acuity difficulties and the cervical lymph nodes were not swollen. A CT scan revealed a large tumor in his left nasal cavity and maxillary sinus which did not extend into the cranial space or eye socket. There were no bone defects. The patient underwent surgery for an olfactory neuroblastoma in June 1997. Based on the pathological findings, we made a diagnosis of olfactory neuroblastoma.<BR>The patient was treated with radiation therapy after surgical therapy.45 Gy radiation therapy was added. The patient was followed up for 1 year and 6 months. In January 1999, there was local tumor reccurence and the tumor invaded his brain. Unfortunately, he died soon after from this local recurrence of his brain tumor in June 1999.
