Abstract

Pyloric gland adenoma is a recently described neoplasia that is very rare. It was first classified as a gastric tumor in 1990. Pyloric gland adenomas occur predominantly in old age, more frequently in women than in men, and they are often found in patients suffering from autoimmune gastritis. The diagnosis can be confirmed by immunohistochemistry, which is strongly positive for MUC6 and MUC5AC, expressed in the superficial layer. A pyloric gland adenoma is a type of gastric tumor, but it has also been reported in the gallbladder, pancreatic duct, duodenum, cervix of the uterus, rectum, and Barrett’s esophagus. In 30% of gastric pyloric adenomas, transition to well-differentiated adenocarcinoma has been noted. Therefore, these lesionsshould be removed. In our case, the lesion was removed by endoscopic submucosal dissection. We report a case of pyloric gland adenoma in the cardia of the stomach showing typical endoscopic and microscopic features. This is the first case of pyloric gland adenoma of the stomach reported in Korea.
