Cytomegalovirus proctitis: a rare and disregarded sexually transmitted disease.

A review of published cases and a recently managed patient is presented, which describes the clinical features of cytomegalovirus proctitis. About half of the reports describe sexually transmitted cytomegalovirus proctitis following anal intercourse, which typically presents with rectal bleeding and a mononucleosis-like syndrome. This condition resolves spontaneously and may be associated with human immunodeficiency virus infection.
