Disseminated ecthymatous herpes varicella-zoster virus infection in patients with acquired immunodeficiency syndrome

Abstract

Herpesvirus infections are among the most common and debilitating opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS), and they may have atypical clinical features. We describe the cases of three patients with AIDS in whom atypical persistent ulcerative skin lesions developed as a result of varicella-zoster virus infection. Two patients had disseminated infection without a vesicular stage; one patient had underlying asteatotic eczema. All responded well to acyclovir. One patient was treated with azidothymidine, and typical dermatomal herpes zoster subsequently developed. The profound loss of helper T cell function in AIDS may lead to multiple abnormalities in local immune response to cutaneous herpesvirus infections and may be responsible for the atypical morphology and a prolonged course.
