Abstract
We report the case of a 56-year-old man with a gastric carcinoid tumor associated with type A gastritis. In December 2010, multiple ulcerative lesions were detected during a barium meal examination. Gastric endoscopy revealed erosive lesions, ulcer scars and multiple small red spots all over the stomach and he was diagnosed with a gastric carcinoid tumor histologically. The serum gastrin level was 1,900 pg/ml. We determined that this gastric carcinoid was associated with type A gastritis and performed laparoscopy assisted distal gastrectomy to decrease the serum gastrin level. The serum gastrin level dropped down to normal range and all carcinoid tumors disappeared.
