[Gastric carcinoid in chronic atrophic gastritis with hypergastrinemia].

A 51 year-old woman with vomitus, intermittent epigastric pain and heartburn had chronic sideropenic anemia. Gastroscopy revealed a subcardial, submucosal tumor. The tumor was removed totally by endoscopic polypectomy. Histologically it was identified as a carcinoid. The endocrinologic examination showed hypergastrinemia caused by chronic atrophic gastritis. The association of this gastric carcinoid with chronic atrophic gastritis type A, hypergastrinemia, hyperplasia of the gastrin-producing antral cells and micronodular hyperplasia of endocrine cells in the gastric fundus, confirms the hypothesis about the pathogenesis of these extremely rare gastric tumors.
