Vulvar intraepithelial neoplasia (VIN) is a condition characterized by abnormal changes in the cells on the surface of the vulva, which is the external part of the female genitalia. VIN is considered a precancerous condition, meaning that while the cells are abnormal, they are not yet invasive cancer.
