Esthesioneuroblastoma

Esthesioneuroblastoma (ENS), also known as olfactory neuroblastoma, is a rare neoplasm originating from olfactory neuroepithelium superior to middle turbinate. They are initially unilateral and can grow into the adjacent sinuses, contralateral nasal cavity and they can spread to orbit and brain. It can cause para neoplastic syndrome by secreting vasoactive petides. Since it can spread intracranially craniofacial resection is the surgery of choice. Combination therapy (Surgery + RT + CT) is used in management.
