Schwannoma of the epiglottis mimicking epiglottic cyst: a case presentation and literature review

Schwannoma of the larynx is a rare entity, accounting for less than 0.1% of all benign laryngeal neoplasms. In particular, schwannoma of the epiglottis is much more rare. We report a case of schwannoma located on the laryngeal surface of the epiglottis which mimicked epiglottic cyst. A 39-year-old female presented with a 5-month history of dry cough. Laryngostroboscopy examination revealed a smooth, predunculated, measuring approximately 1.0 × 1.0 cm mass located on the laryngeal surface of the epiglottis. The patient had suspension laryngoscopy under general anesthesia, with the mass removed by electrotome excision. Based on the histological examination, a final diagnosis of laryngeal schwannoma was made. The patient was free of postoperative complications and had no sign of recurrence. Her dry cough had disappeared immediately after surgery
