We have experienced 20 patients with pernicious anemia (PA) during the last 10 years, and studied endoscopically their gastric mucosal atrophic pattern and complication of gastric cancer. Their family members were also examined when possible. 1) When the mucosa of the whole gastric body was severely atrophic, in contrast to the less severely atrophic antrum, and completely negative of discoloration by the congo-red test, it was defined as "endoscopic reversed atrophic type gastritis". In the cases of this reversed atrophic type gastritis, a border due to difference in severity of atrophy observed endoscopically between the antrum and the gastric body was defined as the reversed atrophic boder. 2) The reversed atrophic type gastritis was observed in 17 (85%) of 20 patients with PA. Reversed atrophic boder was seen in 12 (60%) of 20 PA patients. 3) In 4 of 11 members of the 7 families of patients with PA, a reversed atrophic type gastritis was found. 4) Reversed atrophic type gastritis of PA had relation to the hypergastrinemia, and no relation to the positivity of PCA and IFA. In cases of reversed atrophic gastritis of f ammly members of PA, serum gastrin was elevated as high as in PA, and was related to positivity of PCA and IFA. 5) Gastric cancer was associated in 5 of 20 patients (25%) with PA, including 1 patient with heterochronous double gastric cancer. Lesions were frequently found in the antrum, with a predominance of elevated, differentinated type of carcinomas. 6) A case of gastric cancer was seen in a higher percentage of family members of PA patient than in the families of gastric cancer or peptic ulcer patients.
