Esthesioneuroblastoma (ENB) also known as olfactory neuroblastoma is an uncommon malignant neoplasm arising in the roof of nasal cavity. It is now understood to originate from the olfactory epithelium. Case reports published worldwide have been very few. Common presenting symptoms of Esthesioneuroblastoma include nasal obstruction, epistaxis, facial pain, diplopia, proptosis, and anosmia. Apart from being locally aggressive, it metastasizes widely by both hematogenous and lymphatic routes.
