Paragangliomas of Nasal Cavity: A Case Report

Paraganglioma is a rare neuroendocrine tumor. Nasal localization is very rare. Head and neck paragangliomas represent only 0.6% of head and neck tumors and 3% of all paragangliomas. The treatment is based on surgery. Radiotherapy is indicated if the surgery does not provide complete resection. We report the case of a 36-year-old patient who has had left nasal obstruction with epistaxis for 2 years. The CT scan shows a solid mass centered on the left nasal cavity, puffy, without signs of aggression, benign-looking. The patient underwent a complete endoscopic endonasal tumor removal after preoperative external carotid embolization. Pathological analysis with immunohistochemistry confirmed the diagnosis of paraganglioma. The follow-up to the treatment was favorable.
