Esthesioneuroblastoma is a rare tumor of neural crest origin that arises in the nasal cavity. There is still no consensus on the optimal treatment for this neoplasm, and the literature contains very few accounts of endoscopic excision in these cases. We described a case report of 12-year-old girl with esthesioneuroblastoma that was confined to the nasal cavity and paranasal sinuses, with no orbital or intracranial extension. The tumor was removed via intranasal endoscopic approach and radiotherapy was administered postoperatively. The patient is currently being followed, and there has been no recurrence in 24 months after surgery.
