Cytomegalovirus colitis high power histology

High power view of biopsies of the colon in a patient with cytomegalovirus (CMV) colitis reveals severe acute and chronic inflammation. A lesional cell (circle) with characteristic cytomegaly and both nuclear and cytoplasmic inclusions is diagnostic of a CMV infection. CMV inclusions are usually found in stromal and endothelial cells and rarely in epithelial cells.
