Granular cell tumor, which was referred to historically as a granular cell myoblastoma, is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time. Currently, it is believed that the affected cells are of neural origin. The usual presentation is of a slow growing, nontender nodule. Microscopically, the granular cell tumor can be mistaken for squamous cell carcinoma.
