Figure 7b. Low-grade gastric MALT lymphoma with diffuse nodularity in a 54-year-old woman. The probable diagnosis was lymphoma. (a) Spot radiograph shows numerous nodules of varying size in the gastric body and antrum. (b) Photograph of the resected specimen shows diffuse nodules with distinct margins and variable sizes. (c) High-power photomicrograph (original magnification, x400; hematoxylin-eosin stain) shows diffuse tumor cells and lymphoepithelial lesions (arrows) formed by invasion of individual glands by low-grade lymphoma cells.
