Cytomegalovirus prostatitis. Case report and review of the literature.

We report the case of a patient undergoing chemotherapy for multiple myeloma discovered to have cytomegalovirus prostatitis. The findings of a hypoechoic prostatic lesion on ultrasound and a slightly elevated prostatic specific antigen of 4.6 ng/ml prompted a prostate biopsy. Cytopathologic examination and immunohistochemical staining demonstrated cytomegalovirus within the prostate. This virus is a common pathogen in the immunosuppressed patient, but its presence in the male genital tract is relatively rare. No previous reports of biopsy-proven cytomegalovirus prostatitis appear in the literature. The relationship of cytomegalovirus to the prostate is discussed in detail.
