Heterotopic gastric tissue in the duodenal bulb is a rare congenital lesion. Its prevalence has been reported to be 0.5-2%. It must be differentiated from gastric metaplasia of the duodenal bulb because the two entities have different clinical implications. During one year, we found three cases of gastric heterotopia of the duodenal bulb. In one of the cases, active acid-secreting gastric mucosa was documented by performing the pentagastrin Congo red dye test. The differences between gastric heterotopia of the duodenal bulb and gastric metaplasia of the duodenal bulb have been discussed.
