Randomised trial on treatment of vaginal intraepithelial neoplasia-Imiquimod, laser vaporisation and expectant management.

Vaginal intraepithelial neoplasia (VAIN) is associated with human papillomavirus (HPV) infection. The most common treatment modality is laser vaporisation, but recurrences are common. Imiquimod is an immune response modulator which is used for the treatment of external condylomas and other HPV-related genital neoplasias.
