title: [A case of type IIa early gastric cancer complicated with multiple endocrine cell micronests in pernicious anemia].
abstract: The patient, a 5-year-old male, was diagnosed as having pernicious anemia at our hospital in 1969. By means of an upper G-I series, he was found to have a gastric protruded lesion on the greater curvature of the upper corpus in 1983. After an endoscopic polypectomy, a type II a early gastric cancer was diagnosed which, histologically, showed a well-differentiated adenocarcinoma and a total gastrectomy was performed. From the histologic findings of the resected stomach, the were multiple endocrine cell micronests, that coincided with the distribution of intestinal metaplasia localized in the fundic gland area.
