 A 49-year-old female underwent upper gastrointestinal endoscopy for diagnostic purpose of anemia. A circumscribed, hyperplastic-polyp-like elevated lesion (about 10 mm in diameter) with redness on the surface was found in the greater curvature of the corpus. The biopsy specimen showed carcinoid tumor. The tumor was diagnosed as type I carcinoid associated with type A gastritis, based on the following findings : endoscopic marked atrophy at the fundic mucosa, elevated serum gastrin level (1,900 pg/ml), and positive test for serum anti-parietal cell antibody. Partial gastrectomy was performed. Histological examination revealed that most carcinoid cells proliferated in the mucosa and the lesion had erosion and foveolar hyperplasia on the surface. Compared with previously reported cases of type I carcinoid, macroscopic and microscopic findings of the present case were considered to be typical of type I carcinoid.
