Cytomegalovirus cholangitis in a homosexual man with acquired immune deficiency syndrome.

A 29-year old white homosexual man with acquired immune deficiency syndrome presented initially with right upper quadrant pain and progressive cholestasis. Diffuse mucosal irregularities were seen at endoscopic retrograde cholangiography. Histopathological examination of the gallbladder and wedge liver biopsy showed evidence of cytomegalovirus infection. A repeat endoscopic retrograde cholangiography for persistent symptoms of right upper quadrant pain and cholestasis showed progressive mucosal irregularities of the intra- and extrahepatic bile ducts consistent with progressive cholangitis. Subsequently the patient developed evidence of disseminated infection and died. Postmortem examination revealed histologic features of cytomegalovirus infection in lungs, pancreas, small bowel, adrenal glands, and liver. Immunohistochemical staining of liver confirmed the presence of cytomegalovirus infection of the biliary duct system.
