ABSTRACT
Granular cell tumors (GCT), previously termed granular cell myoblastorna, was first described as a myoblastic myoma of the tongue in 1926 by Abrikossoff and has been reported in many different locations throughout the body. In 1931, Abrikossaff described the first granular cell tumor of the esophagus. The gastrointestinal tract is one of the more uncommon locations for granular cell tumors. Until recently, granular cell tumors had been considered rare but, the incidence of granular cell tumors has been slowly raising since endoscopy has been used more commonly as a diagnostic tool. In this study, we report three cases of esophageal granular cell tumors which were successfully diaganosed by an esophagoscopy and an endoscopic ultrasonography and confirmed using an endoscopic esophageal mucosal resection (EEMR).
