Gastric carcinoid (gastrinoma) associated with achlorhydria (pernicious anemia).
This report presents a case of multicentric gastric carcinoid (gastrin containing) tumors of the fundus associated with achlorhydria and pernicious anemia. It is suggested that stimulation of the antral G cells and possibly fundic argyrophilic cells by achlorhydria associated with atrophic gastritis may lead to hyperplasia, and eventually to neoplasia in the latter, in the form of gastric carcinoid with gastrin production.
