title: [Paraviral exanthems].
abstract: Paraviral exanthems are distinct skin diseases due to infections with different viruses. Although no virus has been identified so far in some exanthems, the main age of manifestation, the clinical course of the exanthem, and the extracutaneous symptoms are suggestive for a viral genesis. While many viral infections are a direct result of the infection, paraviral exanthems reflect the response of the immune system to the infectious pathogens. Viruses cannot be identified in the skin. Typical paraviral exanthems include Gianotti-Crosti syndrome, pityriasis rosea, pityriasis lichenoides, papular-purpuric gloves and sock syndrome, and asymmetrical periflexural exanthema. Unilateral mediothoracic exanthem, eruptive pseudoangiomatosis are rare and eruptive hypomelanosis has been described recently.
