[Granular cell tumor localized in the glottis].

Granular cell tumor is an unusual tumor of probably neuroectodermal histogenesis, originally reported by Abrikossoff (1926) as a myoblastoma. Of the about 1,200 reported cases since then, 50% are found in the head and neck. Of these, 10% have a laryngeal localization. An infrequent case report of glottic localization which was solved by chirurgical excision with free margins, is presented. The features of the laryngeal presentation, is reviewed and iconography with immunohistochemical techniques of their pathologic characteristics, is showed.
