Granular cell tumor of the tongue.

Granular cell tumor is an uncommon benign hamartomatous lesion occurring in almost any part of the body. Granular cell lesions may be found in other diverse sites, such as the jaw, skin, gastrointestinal tract and respiratory tract. The tongue and buccal mucosa are common intraoral sites. The histogenesis of the lesion remains unknown. In this paper, we report the occurrence of an oral granular cell tumor affecting the tongue of a 45-year-old male patient.
