Abstract
The granular cell tumor is an uncommon benign neoplasm with a strong predilection for the oral cavity, with a greater number of cases affecting the tongue. It typically presents as a solitary nodule, asymptomatic, sessile base, with slow growth (months or years) and variable color. Despite its uncertain etiology, studies suggest a neural origin for the lesion. The aim of this article is to present two clinical cases whose main complaint was a submucosal nodules in the dorsum of the tongue, with slow evolution and healthy surface. In both cases, definitive diagnosis was made after histological and immunohistochemical analysis and the treatment was made with conservative surgical excision. It is also discussed clinical, histological and immunohistochemical features of granular cell tumor.
