Figure 1a. Low-grade gastric MALT lymphoma with multiple shallow ulcers in a 31-year-old woman. The probable diagnosis in this patient was gastritis. (a) Spot radiograph of the gastric antrum shows multiple erosions (open arrows) with diffuse enlargement of the areae gastricae (solid arrows). (b) Photograph of the resected specimen shows multiple shallow ulcers (arrows) in the gastric body and antrum. (c) Low-power photomicrograph (original magnification, x10; hematoxylin-eosin stain) shows lymphoma cells (blue stain) diffusely infiltrating the mucosa (m) and submucosa (sm).
