Kaposi's varicelliform eruption.

Kaposi's varicelliform eruption (eczema herpeticum) is the name given to a distinct cutaneous eruption caused by herpes simplex and certain other viruses that infect persons with preexisting dermatosis. Most commonly it is associated with atopic dermatitis. We report a case of a three-year-old atopic child who presented with extensive vesicular eruption suggestive of Kaposi's varicelliform eruption. There was history of fever, malaise and extensive vesicular eruptions. Diagnosis was made based on clinical features and Tzanck smear examination. Patient responded adequately to oral acyclovir therapy.
