title = "The development of foveolar-type gastric adenocarcinoma during maintenance therapy of vonoprazan for reflux esophagitis",
abstract = "We herein report the first case of foveolar-type gastric adenocarcinoma that developed after the initiation of vonoprazan (VPZ). A 51-year-old man had heartburn at the first visit and reflux esophagitis endoscopically, so he started taking VPZ. An approximately 5-mm-sized reddish polyp with a raspberry-like morphology was detected at the anterior wall of the upper body of the stomach 156 weeks after starting maintenance therapy with VPZ 10 mg/day. It was diagnosed as foveolar-type gastric adenocarcinoma based on a biopsy. Another approximately 4-mm-sized foveolar-type gastric adenocarcinoma was also detected at the posterior wall of the middle body of the stomach.",
