A case of laryngeal paraganglioma and literature review.

Paragangliomas are common in carotid body, jugular tympanic cavity and cervical vagus nerve, but uncommon in larynx. We report clinical and pathological features of a 40-year-old woman with laryngeal paraganglioma. Tracheotomy combined with vein anesthesia was performed to isolate tumors. The patient was followed up for 3 months after surgery treatment and recovered well. We also provide a better understanding of this disease through a review of relevant literature. Largnx paraganglioma is rare, but should require long-term follow-up for possible recurrence.
