Abstract

Gastric inverted hyperplastic polyp (GIHP) is a rare type of gastric polyp that has a trend of downward growth into the submucosal layer. We present a case of a heart-shaped GIHP removed by endoscopic submucosal dissection, which needs to be distinguished from gastritis cystica profunda.

Keywords: Gastroscopy, gastric inverted hyperplastic polyp, endoscopic submucosal dissection; gastric fovea; submucosal growth.
