A 73-year-old woman was hospitalized due to anemia. Upper gastrointestinal endoscopy was performed and a large gastric phytobezoar which located from gastric fundus to gastric body was found. The phytobezoar firmly adhered to the gastric wall. We chose endoscopic removal witch involved fragmenting the bezoar with Coca-cola water jet, and direct fracture with snares. We found bleeding from the surface of the resection plane of the phytobezoar, then perfomed biopsy. The biopsy sample contained a small number of atypical cells, so we made a diagnosis of the gastric carcinoma which became a core of gastric phytobezoar.
