title: The congenital cervicovaginal transformation zone in sexually active young women.
abstract: A total of 110 sexually active teenage girls was screened cytologically and colposcopically; 71 of them had areas of aceto-white epithelium within the cervicovaginal transformation zone. Of these 54 had long-term follow-up and over a mean period of 36 months the aceto-white epithelium was observed to disappear in 26. In the remaining 28 girls aceto-white areas persisted largely unchanged over the period of follow-up. The characteristics of these persistent aceto-white areas are documented and suggestions with regard to their origins and significance are made.
