[Vulvar intra-epithelial neoplasms. Development of ideas and facts]

The authors report their personal experience concerning the recent increase in the frequency of VINs and demonstrate how the mean age of the patients has decreased. They advocate "vulvoscopy" and guided biopsy for screening. VIN I and II may be treated with local chemotherapy and/or laser vaporisation. VIN III must be treated surgically (superficial tailored resection).
