Abstract

Fundic gland polyps (FGPs) are currently the most common type of gastric polyps and are usually benign. However, although rare, gastric adenocarcinoma of FGP has been recently proposed as a new variant of gastric adenocarcinoma. Here we report the first case of a 49-year-old woman with focal signet ring cell carcinoma that arose from an FGP of the stomach. The tumor was completely excised by endoscopic snare polypectomy. FGPs should therefore be evaluated for malignant changes although they occur rarely, if the FGP has an erosive or irregular surface.

Keywords: Fundic gland polyp, Signet ring cell

Core tip: We report the first case of a 49-year-old woman diagnosed with focal signet ring cell carcinoma that arose from a fundic gland polyp in the stomach. The tumor was detected and completely excised by endoscopic snare polypectomy. Although malignant transformation of fundic gland polyps (FGPs) is extremely rare, endoscopists should consider the association of gastric polyps with gastric cancer for both hyperplastic polyps and FGPs.
