[Granular cell tumors of the larynx].

Based on four observations of our own and a survey of the 151 cases described to date, the clinical and morphologic results of granular cell tumours of the larynx are presented. These tumours, which were considered as being of myogenic origin ("myoblastic myoma", immature rhabdomyoma", "granular cell myoblastoma" etc.) are probably of neurogenic origin. They develop primarily inthe posterior section of the vocal cords in middle aged males and females. The granular cell tumours remain benign and can usually be extirpated endoscopically without recurrence.
