title: [Multiple gastric carcinoids occurring in atrophic fundic mucosa].
abstract: A 49-year-old man with iron deficiency anemia and achlorhydria was found to have a carcinoid 7 X 4 mm in the upper corpus of the stomach. The subtotally resected stomach histologically revealed 20 carcinoids measuring 0.1-7 mm in largest diameter and numerous argyrophil cell micronests at the base of the severely atrophic fundic mucosa. Some of the lesions invaded down to the submucosa. The antral mucosa was mildly atrophic. All carcinoids and micronests were non-argentaffin and argyrophil, and negative upon immunoreaction with 12 kinds of peptides and amine.
