Histopathological examination results of resected intestinal specimens. HE staining 400 × (a), CMV immunostaining 400 × (b). Pathology shows extensive necrosis and degeneration of the mucosal epithelium, and the mucosal intrinsic layer was replaced by granulation tissue and fibrin with a high inflammatory cell infiltrate. HE staining (a) and CMV immunostaining (b) show nuclear inclusion bodies, indicating CMV infection. There is no evidence of inflammatory bowel disease, granuloma, or vasculitis
