Cytomegalovirus Scrotal Ulcer in a Renal Transplant Patient.

Background: Cytomegalovirus (CMV) is a highly prevalent herpesvirus that can present with cutaneous disease in immunocompromised individuals. This may reflect systemic involvement, which is associated with significant morbidity and mortality.

Objective: To report a case of cutaneous CMV in an immunocompromised patient and to discuss the differential diagnosis of genital ulcers.

Methods: A medical chart review was conducted on a patient who presented with a scrotal ulcer after renal transplantation. A review of the literature on cutaneous CMV disease was also completed.

Results: Biopsy of the scrotal ulcer revealed classic findings of CMV disease. The patient also developed CMV viremia. Treatment with valganciclovir resolved his scrotal ulcer and viremia.

Conclusion: The differential diagnosis for genital ulcers is broad, especially in the immunocompromised patient. Cutaneous CMV disease should be ruled out with biopsy and immunohistochemical examination in immunocompromised patients, as it may reflect systemic involvement and significantly affect patient care.
