Acute varicella zoster with postherpetic hyperhidrosis as the initial presentation of HIV infection.

Abstract

A 31-year-old man presented with acute pain in his left arm and hemorrhagic vesicles that followed his left 8th cervical nerve. A diagnosis of herpes zoster was made, and the patient was treated with valacyclovir. He refused testing for antibodies to HIV because he denied being at risk. Two months later he returned with postherpetic neuralgia and postherpetic hyperhidrosis in the distribution of the vesicles, which had since resolved. Serology for HIV at this visit was positive, and the patient admitted to having sexual relations with prostitutes. Six months later the patient was being treated with triple antiretroviral therapy, and all signs and symptoms of postherpetic zoster had resolved. This case report documents the need for HIV testing in patients with unusual presentations of herpes zoster even if they initially deny being at risk.
