Epithelial gastric polyps can be categorized as being either hyperplastic or adenomatous. Hyperplastic polyps accounts for 75∼90% of gastric polyps. In contrast to the adenomatous polyps, the potential of a malignant transformation of hyperplastic polyps was originally believed to be quite low (an incidence of 1.5∼2.1%), which is considerably lower than that of an adenoma of the stomach. Most of reported cases of a hyperplastic gastric polyp with a transformation to adenocarcinoma were well differentiated histopathologically. There are few reports of a hyperplastic polyp in which malignant changes developed during the endoscopic surveillance. We report a rare case of a 1.2 cm sized moderately differentiated adenocarcinoma arising in a hyperplastic polyp on the cardia in the stomach with a brief review of the relevant literature.
