Abstract

We present a case of localized mucosal hyperplasia of the stomach. The resected stomach contained four large, short stalked polyps, three of which were located in the anterior wall of body and the other in the posterior wall. In addition, numerous small sessile polyps were also scattered in the anterior and posterior fundic walls. Microscopically, the abnormally thick mucosa, carrying with it the muscularis mucosae and a thin core of loose fibrous tissue comprised the polyps by intraluminal infolding of widening of mucosal area. Abundant vasculature of the rugal pattern was prominent in the submucosa. The above findings suggest that the histogenesis of the polyps is related to both hyperplastic thickening and widening of mucosal areas in rugal pattern in the background of inverted distribution pattern of intestinal metaplasia.
