Successful Treatment of Gastric Hamartomatous Polyp with Hemorrhage by Endoscopic Mucosal Resection

Hamartomatous polyp is an uncommon lesion. Most of the gastric hamartomatous polyps occur in patients in their 40s because of polyposis coli. Gastric hamartomaotus polyps are usually asymptomatic, but they occasionally manifest with hematemesis or anemia. If they are congenital, then sessile polyps in children should be observed with some measurable frequency. However, many reports have revealed that if the polyp size is big and the risk of rebleeding is high, then ESD or surgical resection can be used to completely remove them. An inverted gastric hamartomatous polyp may have an early gastric cancer component. We report here on an unusual polyp in a 14-years male who presented with hematemesis. Those were about two 3 cm sized large polyps at the proximal antrum and mid body of the stomach, respectively. The polyps were successfully removed by an endoscopic mucosal resection and the lesions were diagnosed as gastric harmatomas.
