Pediatric laryngeal granular cell tumor.

Granular cell tumor of the larynx is an uncommon, benign tumor which has rarely been described in the pediatric population. Fewer than 10 cases in children under the age of 10 years have been reported. This paper describes two pediatric patients: An eight-year-old boy with a seven-year history of hoarseness due to an anterior subglottic tumor, and an 11-year-old boy with a one-year history of hoarseness due to a left true vocal cord tumor. Subglottic involvement by laryngeal granular cell tumor is rare in adults, but has been seen in half of the reported cases in the pediatric population. The clinical course of granular cell tumor and its pathology are reviewed.
