위궤양반흔부에서 진단되고 악성 Cycle 일부를 보인 조기위암 1예 = A Case of Early Gastric Cancer Diagnosed from the Area of Ulcer Scar and Showing Part of Malignant Cycle

다국어 초록 (Multilingual Abstract)

In the case of IIc type of early gastric cancer occuring from the area of ulcer sear, endoscopic differentiation between it and beoign ulcer scar is occasionally very difficult, due to the absence of characteristic malignant features. The presence of the irregular granular mucosal changes on the area of ulcer scar may be very helpful in the differential diagnosis between early gastric cancer and benign ulcer sear. And underetanding of the malignant cycle of early gaetric cancer is very important for the diagnosis of the depressed forms of early gastric cancer, We experienced and report a cases of IIc type of early gastric cancer diagnosed before operation by the endoscopic finding of irregular granular mucoeal changes on the area of ulcer scar and showing part of malignant cycle.
