Figure 4.

Representative endoscopic findings. (A) Several gastric polyps (arrows) are shown. (B) A retroflexed view shows the gastric cardia. The endoscope is seen as the black tube in the center of the image and is surrounded by a large mass (arrows), consistent with a gastric adenoma with high-grade dysplasia. (C) Endoscopic view of the distal esophagus shows a polypoid lesion (black arrow) and several flat lesions (white arrows). (D) Endoscopic ultrasonographic image of a large cyst (highlighted by arrows) is consistent with an IPMN in the pancreas.
