Figure 1. At low magnification, a gastric adenocarcinoma of the fundic gland type (GAFG) is located in the mucosa (A). The tumor consisted of clustered tumor cells resembling chief cells and cystic glands (B). At high magnification, it is clear that the tumor contains chief cells and parietal cells ➙ (C). Immunohistochemically, the tumors are positive for MUC6 and pepsinogen-I in chief cells, H+/K+ ATPase and PDGFRα in parietal cells (D–G) and are focally strongly positive for β-catenin (H).
