Hyperplastic polyp in gastric polyps is the most frequent type by pathological diagnosis. Most of them are smaller than 20 mm in diameter. We experienced three cases, which had 5 huge gastric polyps type Yamada IV more than 40 mm in size, removed in safety by endoscopic polypectomy. All of their cases had multiple polyps. It is known that huge polyps rarely combine carcinoma cells and have a risk of bleeding and stenosis. We also experienced a focal carcinoma in case 3. It is necessary to remove a huge gastric polyp type Yamada's IV as soon as possible by endoscopic polypectomy.
