Figure 7a. Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach in a 48-year-old man. (a) Image from a double-contrast barium study shows diffuse nodularity of the gastric wall from the high body to the antrum. (b) Photograph of the gastrectomy specimen clearly depicts diffuse nodularity of the gastric mucosa.
