From: Endoscopic features of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type differ between patients with and without Helicobacter pylori infection: a retrospective observational study

Fig. 2

Representative images of oxyntic gland adenoma and gastric adenocarcinoma of the fundic gland type (GA-FG). A A 65-year-old female patient without Helicobacter pylori infection had an oxyntic gland adenoma with a 0-IIa, subepithelial lesion-like morphology in the gastric fornix. The color was similar to that of the surrounding gastric mucosa. B Magnifying endoscopy with narrow-band imaging showed dilatations of the intervening part and the crypt opening. C A 76-year-old female patient with current H. pylori infection presented with a GA-FG with deep submucosal invasion (870 μm) in the gastric fornix. The 0–IIa lesion had a reddish surface and a distinct border, resulting in a non-subepithelial lesion-like morphology. D A 52-year-old female patient had an oxyntic gland adenoma in the atrophic mucosa of the upper gastric body. The lesion was reddish and showed a 0–IIa, non-subepithelial lesion-like morphology. E A 61-year-old male patient with past H. pylori infection had a GA-FG that presented as a whitish, depressed (0–IIc) lesion in the middle third of the gastric body. F A 73-year-old male patient with past H. pylori infection had a GA-FG in the atrophic mucosa of the middle third of the gastric body. The lesion showed a flat (0–IIb) morphology and a yellowish–white color
