Jump to: navigation, search

Vaginal intraepithelial neoplasia (VAIN) is a condition that describes premalignant histological findings in the vagina characterized by dysplastic changes.[1] It is generally asymptomatic.

The disorder is rare and may have no symptoms.[2] VAIN can be detected by the presence of abnormal cells in a Papanicolaou test (Pap smear).[2]

Like cervical intraepithelial neoplasia, VAIN comes in three stages, VAIN 1, 2, and 3.[3] In VAIN 1, a third of the thickness of the cells in the vaginal skin are abnormal, while in VAIN 3, the full thickness is affected.[3] VAIN 3 is also known as carcinoma in-situ, or stage 0 vaginal cancer.[3]

Infection with certain, high-risk types of the human papillomavirus may be associated with up to 80% of cases of VAIN.[4]

One study found that most cases of VAIN were located in the upper third of the vagina, and were multifocal.[5] In the same study, 65 and 10% patients with VAIN also had cervical intraepithelial neoplasia and vulvar intraepithelial neoplasia, respectively.[5]

In another study, most cases of VAIN went into remission after a single treatment, but about 5% of the cases studied progressed into a more serious condition despite treatment.[6]
