There are no standard guidelines for the treatment of granular cell tumor (GCT). The aim of our study was to describe three cases of esophageal GCT and, on the basis of our experience, analyze the indications for and results of their endoscopic treatment. When deciding whether to proceed with surgical or endoscopic resection, endosonography plays a key role in establishing whether the tumor is confined to the submucosa. All three cases were confined within the hyperechoic layer of the submucosa and were successfully treated by endoscopic excision without complications or signs of relapse during the follow-up period.
