Description

<p>In the head and neck region, schwannomas can arise from nerves other than the optic nerves and olfactory nerves, which lack Schwann cells, but such cases are relatively rare. We report a case of schwannoma arising in the arytenoid. The patient was a 54-year-old woman whose chief complaint was hoarseness, which she had been aware of since around 202X. Laryngoscopy revealed a submucosal tumor in the right arytenoid, which caused glottal insufficiency due to tumor volume. The tumor was removed under general anesthesia, and the patient's symptoms improved. The final pathological diagnosis was schwannoma. Neurilemmoma should be kept in mind as a differential diagnosis for laryngeal tumors. It should also be noted that, although very infrequent, head and neck schwannomas have been reported to be malignant.</p>
