Vaginal intraepithelial neoplasia

Vaginal intraepithelial neoplasia refers to different degrees of atypical hyperplastic lesions confined to the vaginal epithelial layer, which is a precancerous lesion of invasive vaginal cancer. Because of the low incidence of intravaginal intraepithelial tumors, their understanding of the process of their evolution into invasive cancer is much worse than cervical and vulvar cancer. Vaginal intraepithelial tumors can coexist with cervical or vulvar intraepithelial tumors.
