Figure 3 Endoscopic findings of ectopic pancreatic carcinoma in a 58-year-old woman. A: A submucosal lesion with central umbilication was observed at the greater curvature of the gastric antrum, accompanied by extrinsic compression near the pylorus (soft on probing, with pyloric patency preserved); B and C: A giant ulcer with raised margins and a white fibrinoid base was found at the duodenal bulb-descending junction, causing significant luminal stenosis; D: The stenosis was nearly obstructive, the tumor in the descending duodenum exhibited mucosal breach and a coarse, irregular surface.
