Ectopic gastric mucosa is known to occur throughout the gastrointestinal tract. Ectopic gastric mucosa in the duodenum is classified into the developmental (heterotopic gastric mucosa) and acquired types (gastric metaplasia). Gastric metaplasia may be present in up to 64% of normal individuals but heterotopic gastric mucosa is quite rare. A heterotopic gastric mucosa in the duodenum may be asymptomatic but can give rise to perforation, hemorrhage, and intestinal obstruction in rare cases. Therefore, periodic endoscopic surveillance is recommended in these cases. Endoscopically, the appearance of a heterotopic gastric mucosa shows a mainly elevated lesion with multiple nodularity. We report a case of 1.5⁓1.2 cm sized polypoid lesion of the duodenum in an asymptomatic 31 year-old man. The mass was resected endoscopically and diagnosed as a heterotopic gastric mucosa.
