Important considerations when contemplating endoscopic resection of undifferentiated-type early gastric cancer

Figure 2 Incorrect T staging: a case of undifferentiated-type early gastric cancer (EGC). A: Endoscopic image of an EGC showing a 10-mm-diameter depressed lesion in the posterior angle of the wall; B: Endoscopic ultrasonographic image showing a hypoechoic mucosal mass with an intact submucosal layer. A surgical specimen obtained upon radical subtotal gastrectomy confirmed that the EGC was confined to the submucosal layer. Taken with permission from Gastrointest Endosc 2007; 66: 901-908[35].
