Abstract

AbstractMost gastric polyps are fundic gland polyps and hyperplastic polyps. Adenomas, inflammatory fibroid polyps, and neuroendocrine tumors are other types of gastric polyps that occur less frequently. Rarely, a gastric polyp may be associated with a syndrome, including hereditary cancer syndromes. Some of these syndromes are also associated with an increased risk of gastric cancer. We present a case of a 50-year-old woman with known Cowden syndrome who presents with multiple gastric hamartomatous polyps. We then review the clinical, endoscopic, and pathologic features of various syndromes that are associated with gastric polyps. Fundic gland polyp–predominant syndromes include familial adenomatous polyposis, gastric adenocarcinoma and proximal polyposis of the stomach, andMUTYH-associated polyposis, all of which are hereditary cancer syndromes. Gastric hamartomatous polyps are found in patients with juvenile polyposis syndrome, Peutz-Jeghers syndrome,PTENhamartoma tumor syndrome including Cowden syndrome, and Cronkhite-Canada syndrome. Syndromic gastric polyps may be biopsied in patients with a previously established diagnosis of the underlying syndrome, such as surveillance endoscopies in familial adenomatous polyposis. On other occasions, the pathologic assessment of gastric polyps may prompt or contribute to a diagnostic workup of an underlying syndrome in conjunction with other clinical and endoscopic findings.
