 To clarify the pathological findings of autoimmune gastritis, we examined 9 surgical and 28 endoscopic cases of biopsy and resection. Initially, lymphocytic and eosinophilic infiltration predominates in the deep mucosa of the fundic gland region, causing the destruction and disappearance of parietal cells. The chief cells are kept relatively, and the fundic glands exhibit pseudopyloric gland metaplasia. When the fundic glands disappear, they are replaced by true pyloric gland metaplasia, intestinal metaplasia, and pancreatic acinar metaplasia. Endocrine cell hyperplasia is also observed. Additionally, the foveolar epithelium demonstrates mild atrophy, cystic changes, and hyperplasia until the terminal stage. In the pyloric gland region, no mucosal atrophy is observed, but findings of bile reflux gastropathy and fibromusculosis within the mucosa is often noted.
