A case of heterotopic gastric fundic mucosa presenting as tightly grouped small elevated lesions occupying the whole space of duodenal bulb, was presented. Acid secretion by these heterotopic gastric fundic mucosa was demonstrated by congo red dye spraying method. A 35-year-old man visited to our hospital because of the epigastralgia. Radiographic examination revealed small elevated lesions which occupied the whole space of duodenal bulb. Endoscopic study showed that small elevated lesions distributed in the whole space of duodenal bulb. The color of these elevated lesions were identical to that of the duodenal mucosa and small red spots were scattered at the top of the lesions. Congo red dye endoscopy revealed the black staining spot at the protruded lesions adjacent to pylorus and the acid secretion from these lesions. Biopsy specimens taken from these lesions revealed the gastric type surface epithelium with well developed fundic glands containing parietal cells and ECL cells. This is a rare case of acid secreting heterotopic fundic mucosa occupying the whole space of duodenal bulb.
