case_images: Staining of the gastric biopsy specimens with hematoxylin and eosin (H&E) revealed severe chronic active gastritis with ulceration and scattered large cells with inclusion bodies, characteristic of CMV infection (Figure 3(a)). Immunohistochemistry (IHC) using monoclonal CMV antibodies was also positive (Figure 3(b)). Duodenal mucosa staining yielded duodenitis and scattered large cells with inclusion bodies (Figure 3(c)).
