Twenty cases of heterotopic fundic mucosa in the duodenum are reported. The patients had several small polyps ranging from one to three mm tightly grouped to form a plaque in a limited zone of the duodenal bulb. In some cases the polyps were separated from one another. They were round or conical and manifested a frosted-glass appearance with a pale-pink or redded coloration. In two cases a whitish solitary polyp of five mm was located in the 2nd part of the duodenum.

Biopsies obtained from the polyps revealed them to be composed of fundal mucosa, thus representing a particular form of heterotopia, other than the steroid-induced type, and that of patients undergoing regular dialysis for uraemia. The different clinical and morphological data in the various forms of fundal heterotopia are discussed.
