These are the most common epithelial polyps of the stomach and are found throughout the stomach, ranging in size from a few millimeters to centimeters. Hyperplastic polyps have been reported in association with various types of chronic gastritis, particularly autoimmune gastritis, Helicobacter pylori gastritis, and the postantrectomy stomach.

Endoscopic Appearance of Gastric Polyposis
The frequency of gastric polyps is gradually increasing due to widespread use of endoscopic examinations. Any discrete lesion protruding into the lumen of gastrointestinal (GI) tract. appeared at endoscopy is called as “polypoid lesion”.However, a polyp is defined as a proliferative or neoplastic lesion of gastrointestinal mucosal layer. Although endoscopic appearances of some polyps may be diagnostic, the term “polyp”should not be used for every discrete protrusions identified at endoscopy unless histopathologically confirme.

Gastric polyps include hyperplastic polyps, adenomatous polyps, fundic gland polyps, and inflammatory fibroid polyps. Unlike polyps of the colon, gastric polyps are rare and have an incidence of less than 1%.

Endoscopic excision of gastric polyps provides a minimally invasive approach to diagnosis and treatment. Polyps smaller than 2 cm are easily snared. Larger polyps or sessile polyps are best removed operatively to obtain a clear margin and complete removal. Occasionally, staged piecemeal endoscopic removal can be performed in patients with severe comorbidities. Wide, local, or segmental resection of the stomach may be performed for multiple polyps, depending on their histology and location. Gastrectomy is justified in patients with diffuse involvement of the stomach by polyps, which can make detection of a synchronous focus of cancer difficult.

Hyperplastic polyps are by far the most common histologic type, and they can vary in location, number, and size. Most are less than 2 cm. Although these polyps harbor no malignancy, they may be accompanied by atrophic gastritis, which predisposes the nonpolypoid mucosa to malignant transformation. Multiple hyperplastic polyps are found in Ménétrier disease. The histology of these polyps is different from that of colorectal polyps in that it shows submucosal edema and faveolar hyperplasia.

Adenomatous polyps (tubular and villous) are usually solitary lesions in the antrum. They have atypical cells and are associated with adenocarcinoma of the stomach. This association is strongest in polyps greater than 2 cm in diameter. The overall incidence of malignant transformation in adenomatous polyps is about 3.4%.

Hyperplastic Polyp of the Gastric Cardias.
These are the most common epithelial polyps of the stomach and are found throughout the stomach, ranging in size from a few millimeters to centimeters. Hyperplastic polyps have been reported in association with various types of chronic gastritis, particularly autoimmune gastritis, Helicobacter pylori gastritis, and the post antrectomy stomach. Long-term use of proton pump inhibitors may be associated with the presence of small gastric fundic gland polyps and hyperplastic polyps.

Antrum Polyps and Gastric Adenocarcinoma
There are several gastric polyps, the video clip display a gastric carcinoma of the corpus.
Gastric polyps are primarily of interest because of their potential relationship to gastric carcinoma. They are almost always asymptomatic and are usually discovered as an incidental finding at an endoscopic examination.

82 year-old female, comes to our endoscopic unit for a second opinion, biopsies reveal both elsewhere and in our endoscopy unit to be an adenoma, patient did not return, probably had changed the diagnosis if this mass had been resected.
