Abstract
This is a case that a 33-year-old woman has had cardialgia as chief complaint. For 9 months before operation, we followed her up by endoscopic and xray examinations. Then, we performed gastrectomy on suspicion of early gastric cancer. We found 12 various shaped, slightly elevated, protuberances over the antrum in resected gastric specimen. Some of them have small raised area of mucous, or valiof ormic type cavity like verruca of an octopus. And others have erosive cavities around the center of snak-like long protuberances or flat ones. Theses changes consisted chiefly of a remarkable hypertrophy of the pyloric gland, and are the same in the structure as adenomatous polyp or regenerative polyp. We could not find any sign of malignancy. Clinical findings of the similar cases have been very rarely reported. It is necessary to differentiate these erosive changes from early gastric cancer, especially elevated type (IIa).
