Article abstract

Patients with zoster sine herpete and Ramsay Hunt syndrome without pathognomonic vesicles at the initial visit are often misdiagnosed with Bell's palsy and treated without antiviral agents. With PCR, we found that varicella zoster virus genomes were frequently detectable in auricular skin exudate from patients with zoster sine herpete or Ramsay Hunt syndrome before the appearance of vesicles.
