Cytomegaloviral epididymitis in a patient with the acquired immune deficiency syndrome.

We report on a patient with cytomegaloviral epididymitis and the acquired immune deficiency syndrome. The diagnosis was suggested by epididymitis that was refractory to antibiotics, and by isolation of cytomegalovirus from the urine and semen. The definitive diagnosis was made with immunohistochemical staining for cytomegaloviral antigens in the epididymal ductal cells. Because of the ineffectiveness of antimicrobial agents in this disorder, epididymectomy is the current treatment of choice.
