22. Cutaneous involvement by cytomegalovirus in a renal transplant recipient as an indicator of severe systemic infection
Abstract Cytomegalovirus is an opportunistic virus that commonly affects immunosuppressed patients. Cutaneous involvement by this virus is rare and occurs in significantly immunocompromised hosts, with a poor prognosis.
