 In order to clarify the clinicopathological features of 23 gastric cancers in 20 patients with autoimmune gastritis, we retrospectively investigated 95 patients with autoimmune gastritis for 12 years. Most subjects had differentiated adenocarcinoma of the elevated type in the gastric corpus. Twenty-two lesions except SCC were early gastric cancers. More than half the lesions had gastric type of mucus phenotype. Among 23 lesions, three were gastric adenocarcinoma of the fundic gland type, and one lesion was SCC. Patients with gastric cancers tended to have more gastric hyperplastic polyps and stronger degree of chronic inflammation and atrophy of the gastric corpus.
