Gastric heterotopia of the small intestine is a rare occurrence outside of Meckel's diverticulum and intestinal duplication. The vast majority of cases of gastric heterotopia occur as polypoid or tumorous lesions in the duodenum. These lesions have been associated with clinical symptoms including diarrhea, obstruction, dyspepsia, ulceration, and gastrointestinal bleeding. We present a case of gastric heterotopia that is unique because the lesions occurred as multiple, carpet-like, nonpolypoid areas throughout a large portion of the small intestine. A review of the literature is included.
