Perineal ulcers in an infant: an unusual presentation of postnatal cytomegalovirus infection.

Cytomegalovirus (CMV) disease can cause significant morbidity and mortality in neonates and immunosuppressed patients. Cutaneous disease is rare, even in at-risk patients. We report a case of CMV with perineal papules, erosions, and ulcers in a preterm but presumably immunocompetent patient, whose diagnosis was first suggested by skin biopsy and confirmed with serologic testing. The mode of transmission of CMV was unclear. The lesions resolved without CMV-specific therapy, and the child had no apparent systemic sequelae of infection. CMV disease should be considered in the differential diagnosis of perineal erosions and ulcers in infancy. In addition to the case, we briefly review the literature on cutaneous manifestations of CMV disease.
