Cytomegalovirus infection of a cutaneous ulcer in a patient with ANCA-positive vasculitis.

This case describes a patient in whom cytomegalovirus (CMV) infected a preexisting ulcer. The patient was immune-suppressed because of treatment for Wegener's granulomatosis. Specific antiviral therapy was delayed because of uncertainty as to the role of CMV, but the infection cleared and the ulcer improved promptly on institution of valganciclovir.
