Fourteen minute gastric carcinoid lesions were demonstrated in 3 resected stomach. Endoscopical and histopathological studies on the developement of carcinoid tumor were carried out about these lesions. We could recognize endoscopically only 6 lesions in diameter of more than 2mm which already invaded to submucosa. Our findings disclosed that the carcinoid lesions developed from deep portion of gastric mucosa and easily invaded to submucosa. At first, the mucosa is apparently lifted slightly and the lesion indicated to hemispherical appearance. The lesion in 5mm diameter has the bridging fold as a submucosal tumor. The lesions in growth accompanied ulceration and metastased to regional lymph node.These findings revealed that the radical gastrectomy as gastric cancer are necessary, when carcinoid lesions are demonstrated.
