Representative endoscopic images of oxyntic gland adenoma and/or gastric adenocarcinoma of fundic-gland type. (A) A typical image of oxyntic gland adenoma showing a slightly whitish, elevated lesion of 5 mm, with vascular dilatation on the surface. (B) A representative image of gastric adenocarcinoma of fundic-gland type (T1b1) presented as a slightly yellowish, elevated lesion of 7 mm, with vascular dilatation. (C) An oxyntic gland adenoma showing a flat, whitish lesion (linked color imaging). (D) A gastric adenocarcinoma of fundic-gland type (pT1b1) showing a flat lesion. The color of the lesion is similar to that of the peripheral gastric mucosa. (E) Gastric adenocarcinoma of fundic-gland type (T1b2) presented as the largest tumor (25 mm, arrows). The lesion is composed of swollen gastric folds and a whitish, depressed area in the center (arrowhead). Vascular dilatation is observed throughout the lesion. (F) A gastric adenocarcinoma of fundic-gland type (pT1b1) accompanying black pigmentation (arrows).
