pernicious anemia, atrophic or achlorhydric gastritis, and other conditions that produce decreased gastric acidity are thought to promote the development of hyperplastic polyps and are associated with a high risk of gastric cancer in adults. Indeed, patients with pernicious anemia have a risk of developing gastric adenocarcinoma triple that of general population [1]. The risk that hyperplastic polyps will develop into other histo-logical types of cancer ranges from 0 to 4.5%, but their existence justifies endoscopic resection and histopathological study. We report a case of pernicious anemia in which degenerative changes occurred to hyperplastic polyps.
