title: Vaginal intraepithelial neoplasia. Report of 14 cases.
abstract: From 1978 to 1985 we have found 14 cases of vaginal intraepithelial neoplasia (VAIN) in patients previously hysterectomized. VAIN was detected by an abnormal cytology; diagnostic process included a second cytology, colposcopy, Schiller test, and directed biopsies. VAIN was classified as grade I in 5 patients (35.7%); grade II in 5 patients (35.7%); and grade III in 4 patients (28.6%). Pathogenic classification of VAIN was: VAIN de novo 9 cases (64.3%); VAIN after vaginal irradiation, 3 cases (21.4%); VAIN following incomplete removal of a cervical intraepithelial neoplasia, one case (7.1%); and VAIN as manifestation of a multicentric neoplasia of the lower genital tract, one case (7.1%). The mean time between hysterectomy and VAIN diagnosis was 6.9 years; this time was larger for those women hysterectomized by benign uterine diseases (9.0 years vs. 2.4 years). Our conclusion is that patients who have lost their uterus by malignant or benign diseases should be followed-up with periodic vaginal cytology in order to detect vaginal neoplasia in its pre-invasive stages.
