Esthesioneuroblastoma: A case report and review of the literature.

Esthesioneuroblastoma (ENB) is an extremely rare malignant neoplasm of the nasal cavity. We report the case of a middle aged man who presented with a 6-months history of progressive nasal obstruction, watering of the eye, headache and occasional epistaxis. A diagnosis of esthesioneuroblastoma was established by histopathology and confirmed by immunohistochemistry. On staging the mass was classified as a kadish stage C tumor. The mass was excised via a craniofacial resection through a bi-coronal approach and the tumor mass was peeled away completely from the frontal lobe dura. The patient underwent postoperative radiation, and he was free of recurrence at follow-up 3 months later.
