Varicella zoster virus (VZV) infections are known to be atypical and severe in immunocompromised patients. An eight-year-old girl presented with extremely painful, atypical skin lesions and features of meningitis and pneumonitis. On investigation, she was found to be human immunodeficiency virus (HIV) infected, with very low CD4 count. A diagnosis of 'progressive varicella syndrome' was made, and the child was started on antiretroviral therapy and IV acyclovir. This resulted in a complete resolution of all the clinical features. However, the skin lesions promptly relapsed when acyclovir was withdrawn. Oral Acyclovir was started, and had to be continued to keep the disease under control.
