Abstract

A 59-year-old man underwent endoscopic mucosal resection (EMR) for gastric adenoma. He had suffered from end-stage renal disease for several years and had received renal transplantation some 5 months before EMR. Subsequently, he took immunosuppressive agents. Follow-up gastrofiberscopy 6 months after EMR showed a sessile polyp at the resection site twice as large as the original adenoma; biopsy specimens revealed a hyperplastic nature. At the time of writing, this hyperplastic polyp has neither increased in size nor developed adenomatous or carcinomatous changes by histological examinations over the past 5 years. Therefore, this is a case of hyperplastic polyp occurring at the gastric adenoma resection site, and suggests the possible effect of immunosuppressive therapy on the post-EMR healing process and hyperplastic polyp development.
