RESUMO

Vulvar carcinomas represent 4% of all gynaecological cancers with 838 new cases in France in 2018. The precursor lesions of vulvar carcinomas are differentiated vulvar intraepithelial lesion (dVIN) in a context of lichen sclerosus and vulvar high-grade squamous intraepithelial lesion (HSIL) link to human papillomavirus (HPV) infection. Three typical clinical forms of HSIL are described: the Bowenoid papulosis, the Bowen's disease and the confluent VIN. Histopathology cannot differentiate effectively these two types of lesions. P16 and P53 immunostaining are valuable tools to respectively assess HPV infection and divide different types of dVIN. However, P53 immunostaining is still lacking sensibility to detect dVIN. First line therapies are medical treatment excluding the cases with a doubt of invasion. The gold standard treatment for dVIN and vulvar HSIL are respectively topical corticosteroids and imiquimod. Primary prevention for vulvar HSIL and dVIN are respectively HPV vaccination and early treatment of lichen sclerosus. Destructive therapy can be used in case of medical treatment failure such as CO2 laser, cryotherapy, dynamic phototherapy. Surgical indications should be carefully assessed between the risk of recurrence, the spread of the lesions, the aesthetic and functional aspect. Surgical procedures consist in either superficial vulvectomy or radical vulvectomy with or without flap reconstruction. Recurrence rate after surgery is around 20%.
