A 40-years-old woman reporting difficulty in swallowing and diagnosed elsewhere with a submucosal tumor of the esophagogastric junction was further diagnosed with a submucosal cyst originating in the fourth-layer stomach wall directly beneath the esophagogastric junction. Due to the difficulty in swallowing and possible malignancy, we conducted proximal gastrectomy and reconstructed the jejunum interposition. Pathologically, we confirmed underdeveloped cilia on the inner side of the cystic wall and a nucleus in the base and central part, suggesting that tissue originating in esophagus had become aberrant beneath the esophagogastric junction. The cystic lesion in the stomach was reported as a gastric cyst, the other side as enterogenous cyst or as duplication cyst. We confirmed the cyst with underdeveloped cilia on the inner side of the cystic wall directly beneath the esophagogastric junction.
