 A minute early gastric cancer of Ⅱb type, measuring only 3 by 3 mm, was preoperatively diagnosed by endoscopy and aiming biopsy. The lesion had been first found in the course of roentgenological examination.

 The patient, a 45-year-old woman with a chief complaint of epigastric discomfort, was pointed out to have an abnormality in the greater curvature of the antrum by a roentgenological examination. She was referred to the author's hospital.

 On admission, barium-filled radiograph in upright position showed irregularity of the greater curvature of the antrum. Double contrast radiograph in supine position showed irregularity and regidity of its wall more clearly, especially in the oral side. Double contrast radiograph in prone position demonstrated areae gastricae of unequal size and faint barium flecks suggesting a small depressed area. In double contrast radiograph in supine first oblique position, irregular areas and linear barium flecks in between were noticed.

 Endoscopical study revealed a protrusion slightly engorged, measuring about 5 mm in diameter, on the greater curvature of the antrum. Of 6 pieces of biopsy speicimens, 2 showed Group Ⅳ and operation was performed.

 Gross finding of the resected stomach in fresh and half-fixed specimens showed an erosive lesion on the greater curvature of the antrum.

 Histologically, the lesion was papillary adenocarcinoma, measuring only 3 by 3 mm, localized within the mucosal layer.
