A 56-year-old male was admitted to our hospital for the further examination of an elevated lesion in the gastric body which had been detected by X-ray. Endoscopic examination showed a small elevated lesion on the posterior wall near the greater curva-ture of the body of the stomach. The endoscopic biopsy from the depressed area led to the histological diagnosis of carcinoid tumor. The endoscopic ultrasonography (EUS) revealed a hypoechoic tumor extending from the 2nd layer to mainly (the 3rd layer) of the gastric wall without change below the 4th layer. Gastric resection was performed. The tumorous invasion was limited to the submucosal-layer of the gastric wall. This finding corresponded to the preoperative diagnosis by EUS. Application of EUS for gastric carcinoid has not been so far reported. EUS was expected to be useful to diagnose the degree of the extent of carcinoid tumor, contributing to the determination of operative procedure.
