What are vulvar squamous intraepithelial lesions?
Low grade squamous intraepithelial lesions (LSIL), high grade squamous intraepithelial lesions (HSIL) and differentiated vulvar intraepithelial neoplasia (dVIN) are the names given to the presence of abnormal squamous cells on the vulvar skin. These areas can occur as one patch or they may affect several areas of skin at the same time.
These lesions are not cancer. LSIL are also known as warts. They do not become cancer and don’t need treatment unless they are causing symptoms. HSIL and dVIN may develop into cancer if not treated.
