Case report of olfactory neuroblastoma

ABSTRACT

Olfactory neuroblastoma is an uncommon malignant tumor(just over 300 cases have been reported in the medical literature by 1996) arising within the nasal cavity. This tumor has a neuroectodermal cell origin and is believed to specifically arise from the olfactory epithelium. The tumor was first described in the French medical literature by Berger and associates in 1924 by the name esthesioneuroepitheliome olfactif. The english version of this term is esthesioneuroblastoma, and current medical literature uses this name interchangeably with olfactory neuroblastoma. We experienced a case of olfactory neuroblastoma in the maxillary sinus. We treated this patient with tumor resection, chmotherapy and radiotherapy. And now, the patient has been following up for 2years 6month, but olfactory neuroblastoma is very rare. So we report this case with a review of literature.
