Vulvar intraepithelial neoplasia (VIN) is one of the rarest vulvar pathologies and its diagnosis is a challenge for gynecologists. Since lesions of the VIN type are believed to be precursor lesions of vulvar squamous cell carcinoma, their early detection and treatment are significant. Currently, 2 types of VIN are distinguished: uVIN, the occurrence of which is associated with human papilloma virus (HPV) infection, and dVIN, which is independent of infection. The paper presents a detailed description of the latest VIN classification, evolution of nomenclature, basic aspects of epidemiology, etiology as well as characteristics of macro- and microscopic lesions.
