Abstract
This paper describes a case of granular cell tumor (GCT) of the esophagus, of which was detected incidentally by the demonstrational use of new two channel endoscope.
A 24-year-old female underwent an endoscopic examination as a volunteer for the demonstrational use of new endoscope.
Endoscopic examination showed a yellowish white sessile protruding lesion in the lower esophagus. Because the obtained specimen by forceps biopsy was too small to make a diagnosis, two channel endoscope was inserted and boring biopsy was performed by holding the root of the tumor with snare forceps. The obtained specimen was sufficient to make a diagnosis. EUS disclosed that the tumor had no invasion to submucosal and proper muscle layer, thus we adopted endoscopic treatment for GCT removal. Endoscopic resection should be taken into consideration as the first choice when the tumor is limited to the mucosal and submucosal layers.
