Four cases of esophageal granular cell tumor were treated using method of endoscopic esophageal mucosal resection (EEMR) . Either electric knife or guide-tube was employed with electric snare to complete EEMR method. All the tumors were entirely resected by this method, though one case suffered from fever and pleural effusion after treatment.
Granular cell tumor sometimes appears as malignant tumor, therefore entire resection of this tumor using EEMR method should be recommended in stead of incomplete resection using endoscopic polypectomy method.
