術前診断しえた食道・胃同時性早期重複癌の1例

Abstract

A 64-year-old man was admitted to our hospital because of an abnormal finding of the esophagus detected by a barium meal examination on a medical check up. Barium meal study revealed a slightly elevated lesion at the middle esophagus, but no finding at the stomach. By an endoscopic examination, this elevated lesion was surrounded by a slightly reddish mucosa, which was not stained by the Lugol application. Endoscopic examination of the stomach showed a depressed lesion at the posterior wall of the lesser curvature at the upper stomach. Biopsied specimens of the esophageal lesion showed squamous cell carcinoma and those of the stomach were tubular adenocarcinoma. Pathological examination revealed superficial elevated type associated with superficial flat type limited to the mucosal layer at the esophagus (IIa+IIb type, 4.7×4.7cm in diameter) and superficial depressed type limited to the mucosal layer at the stomach (IIc type, 0.8×0.8cm in diameter) . The occurrence of ealry esophageal carcinoma with early stomach carcinoma is rare. Only 36 cases have been reported in Japan. This case was diagnosed as the early esophageal carcinoma and the early gastric carcinoma before the operation was performed.
