Lymphoid Hyperplasia of the Stomach Presenting as Umbilicated Polypoid Lesions

Two cases of benign lymphoid hyperplasia of the stomach manifested by multiple small, umbilicated polypoid lesions are reported. The different radiological manifestations in the stomach are discussed and compared to those in the duodenum, colon, and rectum, with emphasis on the possible role of gastric acidity. Presenting symptoms were sour eructation, indigestion, anorexia, nausea, weight loss, and probably bleeding. The lesions did not respond to a conventional ulcer regimen.
