Summary
Granular cell tumor (GCT) of the larynx is an uncommon, benign laryngeal neoplasm.
Abrikossoff first described the tumor in 1926 as myoblastoma. The origin of this tumor
has been debated in the literature. Most of the authors believe that the tumor is
of neural origin due to the characteristic immunohistochemical-staining pattern. The
authors describe two cases of laryngeal GCTs located in different sites with a review
of the histological and clinical features, the differential diagnosis, and the treatment
and the prognosis of the tumor.
