introduction: paragangliomas are neuroendocrine tumors that most commonly originate in the adrenal gland, a type that is called pheochromocytoma; however, 5-10% of paragangliomas are extra-adrenal and may arise in any area between the neck and pelvic region along the sympathetic nervous system. those located in the head and neck comprise 3% of extra-adrenal tumors, with the majority originating in the tympanic-jugular region and carotid body. objective: to present a rare case of nasal paraganglioma and review the literature. case report: the patient was submitted to medial subtotal maxillectomy, and her clinical findings, diagnostic data, and treatment outcome were recorded. conclusion: paragangliomas are considered benign tumors, but they occasionally display a malignant character. the most important finding in this case was the need for total resection of the tumor to avoid recurrence.
