 We studied the findings concerning gastric carcinoma with the appearance of a submucosal tumor of the stomach, using endoscopic ultrasonography (EUS). Gastric carcinoma with scirrhous invasion with the appearance of a submucosal tumor showed thickening of the 3rd and 4th layers on EUS. Mucinous adenocarcinoma of the stomach with the appearance of a submucosal tumor showed a well-defined and slightly hyperechoic mass in the 3rd layer on EUS. Gastric carcinoma with lymphoid stroma with the appearance of a submucosal tumor showed a well-defined and homogeneous hypoechoic mass in the 3rd layer on EUS. It is difficult to distinguish whether the lesion is carcinoid tumor or malignant lymphoma. Gastric carcinoma accompanied by submucosal cysts with the appearance of a submucosal tumor had a round-shaped and anechoic area beneath the tumor in the 3rd layer on EUS.

 EUS can provide useful information for the differential diagnosis between submucosal tumor and carcinoma with the appearance of a submucosal tumor of the stomach.
