Olfactory neuroblastoma is a rare malignant tumor of neural crest origin, arising in the nasal cavity. We encountered three cases of olfactory neuroblastoma : Case 1, in which the tumor had invaded to the ethmoidal sinus, Case 2, in which the tumor was limited to the nasal cavity, and Case 3, in which the tumor had invaded the anterior cranial fossa.
All 3 patients were treated with a combination of surgery, radiotherapy, and chemotherapy. All of the patients are still alive without any evidence of recurrence.
