Abstract

Background: Laryngeal schwannomas are rare benign tumors of schwann cell origin and commonly present in the supraglottic area. Patients present with non-specific symptoms such as dysphagia and dysphonia with the occasional patient presenting with more severe symptoms such as stridor. Case Presentation: A 65-year-old female presented to the clinic with symptoms of hoarseness and globus sensation for three months. Fiberoptic flexible nasolaryngoscopy revealed a mass at the right arytenoid, appearing consistent with a mucosally covered cyst-like lesion. Computed Tomography (CT) of the neck showed a lobular hypoenhancing mass at the level of the aryepiglottic fold. A schwannoma was diagnosed via histopathology, positive for S-100. Conclusion: Tailored surgical excision via an intraoral approach successfully removed the laryngeal schwannoma with no recurrence at one-year follow up. This case highlights the clinical presentation, diagnosis, surgical treatment with outcome of this rare laryngeal tumor.
