Granular cell tumors of the larynx: diagnosis and management.

In this case study, a retrospective review of chart and literature was done to discuss the presentation and treatment of granular cell tumors of the larynx. One patient was diagnosed and treated successfully with surgical resection of a laryngeal granular cell tumor. Excellent voice recovery was obtained and there is no evidence of recurrence 6 months after surgery. Granular cell tumors should be considered in the differential diagnosis of laryngeal masses, particularly in the posterior glottis.
