Chronic verrucous varicella-zoster infection in a patient with AIDS.

The expression of herpes varicella zoster virus in patients already infected with the human immunodeficiency virus (HIV) provides the perfect illustration of an opportunist microbe at work. There is an increased incidence of herpes zoster which may be more severe, recurrent or disseminated. Likewise, varicella may be more severe and recurrent. In both patterns of infection atypical lesions in the form of persistent ulcerative or verrucous lesions have been seen. An HIV-positive patient is described who developed verrucous lesions de novo, 4 months after her child had varicella.
