Granular cell tumor of the larynx in a 5-year-old child

The youngest reported case of laryngeal granular cell tumor is presented together with transmission electron micrographs of the tumor cells. Whereas subglottic involvement is unusual in adults, a review of the literature reveals that three of the seven youngest patients (including the present patient) with laryngeal granular cell lesions had a subglottic tumor immediately below the anterior commissure.
