Cytomegalovirus colitis is a type of colitis caused by cytomegalovirus.
General
- Uncommon.
- Immunosuppressed population at risk, e.g. transplant recipients, individuals with HIV.
- Typically self-limited in immunocompetent patients.[1]
Microscopic
Features:
- Enlarged nucleus - typically in endothelial cells.
- Nucleus classically has peripheral clearing - described as "owl's eye".
- Epithelial cells and lamina propria cells may also be affected.[2]
DDx:
- Infectious colitis without a distinctive morphology.
- CMV colitis superimposed on inflammatory bowel disease.

IHC
- CMV +ve.
- Increases the sensitivity (compared to H&E alone).[3]
Others:
- HSV-1.
- HSV-2.
- VZV.
- EBV.
