Varicella-Zoster Virus Vasculitis: A Case of Recurrent Varicella without Epidermal Involvement

New types of diseases due to the varicella-zoster virus (VZV) are increasingly recognized. A case of cutaneous VZV vasculitis without epidermal involvement is presented. The patient received chemotherapy for a large B cell lymphoma. He presented a few painless papules on one hand and in the axilla. A lymphocytic vasculitis was evidenced. Immunohistochemistry revealed the presence of VZV in endothelial cells and dermal dendrocytes. Nerves and keratinocytes were free of the virus infection. Such a presentation probably represents a mild form of recurrent varicella with prominent but limited vascular involvement.
