 Fundic gland polyp is one of the most common gastric polyps. In familial adenomatous polyposis patients, fundic gland polyps tend to be more numerous than those found in sporadic cases, and occur in the fornix and the greater curvature of the gastric body. Fundic gland polyp is histologically characterized by proliferation and cystic dilatation of the fundic gland mucosa, and it is known to be a hamartomatous lesion with no malignant potential. Recently, progress in molecular studies have revealed that fundic gland polyp is caused by mutation of APC or β-catenin. Recent reports also have described frequent dysplastic change in its foveolar epithelium. We briefly review recent reports, including molecular studies, regarding dysplasia and tumorigenesis related to fundic gland polyp.
