Olfactory neuroblastoma (ON), also called Esthesioneuroblastoma (ENB) is a rare malignant nasal tumour that arises from the olfactory neuroepithelium in the olfactory rim of nasal cavity. Here, we present a case series of two patients who presented with nasal obstruction, epistaxis and anosmia. Clinical examination revealed reddish mass within the nasal cavity and extending into the nasopharynx. An endoscopic craniofacial resection was done and biopsy confirmed the masses to be olfactory neuroblastoma.
