The C Hepatitis, it is a RNA virus of the Flaviviridae family, that introduces within their spectra of infection, manifestations liverworts and extrahepatic, being these last few frequent. Crioglobulinas could be detected in a third of patient with C hepatitis, but in only 1-2% of the cases develop cutaneous manifestations, some of this manifestatios are vaculitis with acronecrosis. The infection for C hepatitis occurs in other countries with diferent prevalence, they have more prevalence than in our countrie, being different to the prevalence for other types of viral hepatitis (B hepatitis).
