Schwannomas originating from Schwann cells are well capsulized benign tumors, and are not common in the larynx. In Japan, the first case was reported in 1948. Since then, only 73 cases have been reported to our knowledge. We describe a schwannoma of the larynx in a 60-year-old woman who had suffered from hoarseness for 40 years. The lesion was located in the right false cord of the larynx, and was found to be a submucosal tumor. It was removed by thyrotomy, and the diagnosis was confirmed pathologically. In this case, the mobility of the right vocal cord was impaired after surgery. Therefore, the possibility that the tumor originated in the recurrent laryngeal nerve branch is discussed.
Key words : Schwannoma, larynx, thyrotomy
