A Rare Laryngeal Schwannoma in an 11-Year-Old Boy.

Schwannomas account for a large proportion of tumors in the head and neck regions; however, schwannomas of the larynx are rare. An 11-year-old boy had a sore throat for one month, and his symptoms gradually worsened such that he needed to visit our otolaryngology clinic. The preoperative investigation revealed a smooth mass in the left arytenoid cartilage. Endoscopy-assisted transoral resection of laryngeal masses was performed under general anesthesia, and the resected tissue was histopathologically diagnosed as a laryngeal schwannoma. The postoperative recovery was very good. During the 1-year follow-up, there was no recurrence of the schwannoma or related symptoms. Although laryngeal schwannomas are rare, they should be considered in the differential diagnosis of these tumors. Sufficient preoperative imaging should be performed before surgical resection, and surgery is the preferred treatment option.
