患者：岸○江　44歳　女

主訴：空腹時の上腹部痛

現病歴：昭和40年11月頃より空腹時の上腹部痛が出現，某院を受診．胃X線検査，胃カメラ検査で胃潰瘍といわれ，約40日間，投薬をうけたが，上腹部痛は消失せず，昭和41年1月，精査のため当科外来を受診した．

　A case of early gastric cancer is reported of superficial depressed type, Type Ⅱc, located on the greater curvature. It was correctly diagnosed prior to the operation.

　Marked convergence of mucosal folds and elevation of gastric mucosa are seen surrounding cancerous ulceration. These findings are characteristic of lesion on the greater curvature side of the stomach.

　In bariumfilled X-ray study, an indentation and irregularity of the gastric wall are noted, while in double contrast view, abrupt cessation of mucosal folds with their slender ends are visualized. In proportioned compression study is also recognized an irregularly outlined barium depot with discontinued folds and their slender ends.

　By endoscopy, a depressed lesion is seen with irregular exudate over it as well as surrounding rugged area and interrupted folds.

　Pathohistologically this lesion is confirmed as adenocarcinoma tubulare with slight mucosal involvement, located on the greater curvature of the lower gastric body.
