[Cell patterns induced by human papilloma virus in samples sent to a cytodiagnostic central laboratory]

Virus induced changes occur not so rarely in combination with precancerous and cancerous lesions. We compared the cytological and histological findings. The increasing frequency of this event is demonstrated by an analysis of the material seen in our laboratory, smears from more than 120,000 patients per year. It was possible to verify the viral etiology by the electron microscopical demonstration of virus particles.
