Abstract

Brunner's gland hamartoma, also called as Brunner's gland adenoma or Brunner's gland hyperplasia, is a relatively rare disease that results from benign proliferation of the Brunner's gland normally present in the duodenum. It is mostly located at the duodenal bulb, occasionally second or third portion, but is rarely found at the pyloric ring, jejunum or proximal ileum. In Korea, total 27 cases of Brunner's gland hamartoma have been reported, but none of them had their origin at the pyloric ring only. We report a case of Brunner's gland hamartoma, found incidentally, originating from the pyloric ring in a 54-year-old woman, which was resected endoscopically after retracting the tumor into the stomach.
