Olfactory neuroblastoma: A case report

Abstract

Olfactory neuroblastoma (ON) is a rare malignant neuroectodermal tumor of the nasal cavity. The malignancy accounts for <3% of tumours originating in the nasal cavity. Through the nasal cavity, ON may infiltrate the sinuses, the orbit and the cranium. The tumour is characterized by a pattern of slow growth and local recurrences. Olfactory neuroblastoma is a neoplasm that can histologically mimic many tumours within the sinonasal tract. Treatment options are surgical excision combined with a radiotherapy and/or chemotherapy combination treatment.The present study reports the case of a 45 year-old male patient with a mass in the nasal cavity who was treated by combined surgical excision and radiotherapy. The literature for ON and the treatment of the tumour are also discussed.
