Gastric Hyperplastic Polyp Occurring at the Resection Site of Gastric Adenoma

Endoscopic mucosal resection was carried out in a 70-year-old man with a gastric adenoma. Endoscopy 1 year later revealed a subpedunculated polyp about 1 cm in diameter at the resection site. Pathological examinationof the resected specimen showed hyperplasia of the regenerative epithelium. The mechanism of occurrence of hyperplastic polyp at the resection site is discussed.
