Endoscopy showed a slightly depressed-type tumor at the esophageal side of esophagojejunal anastomosis (fig. 1a), with a diameter of about 20 mm. Endoscopic ultrasonography showed thickening of the submucosal layer (fig. 1b). Macroscopically, the tumor was a slightly depressed-type tumor, measuring 18 x 15 mm, extending to the esophagus from the anastomosis (fig. 1c). On the basis of histopathological examination, mucinous adenocarcinoma (pT1, pN0, sH0, sP0, sM0, PM-, DM-, stage IA) was diagnosed (fig. 1d).
