Granular Cell Tumor of the Larynx in a Six-Year-Old Child: Case Report and Review of the Literature

Abstract

Granular cell tumors (granular cell myoblastomas) are uncommon neoplasms in the adult population, occurring predominantly in the head and neck and most frequently in the tongue. Laryngeal presentations are unusual, and granular cell tumors of the larynx in children are extremely rare, with a total of 19 cases reported in the literature in children under the age of 17 years. We report an additional case of a laryngeal granular cell tumor, in a six-year-old boy, and discuss the clinical, histologic, ultrastructural and therapeutic aspects of these neoplasms.
