This picture shows the same case seen in Image:Adenocarcinoma of the stomach.jpg

This is a longitudinal section cut in the plane of the lesser curvature. The pylorus is to the left. Note several prominent nodes of the lesser omentum; these contained metastatic cancer.

A more subtle featue of the cancer can be seen by comparing the gastric wall on the left and right sides of the ulcer. To the left, the normal anatomic layers (mucosa, submucosa, muscularis propria, and serosa) are clearly identifiable, and no tumor is grossly present. The wall to the right of the ulcer also shows identifiable anatomic layers, but they are all cemented together by the white carcinoma that extends between the layers, like icing in a layer cake.
