title: [Precancerous changes in the epithelium of the cervix uteri: terminology and principles of differential diagnosis].
abstract: Three most popular classifications of precancerous changes in the epithelium of the cervix uteri, their merits and demerits, morphological criteria, and principles of differential diagnosis are considered. The advantage of the SIL classification is the more accurate reflection of the biology of the process and a common terminological base proposed for histological and cytological classifications, which is particularly important to overcome difficulties in clinical interpretation. LGSIL provides a high rate of diagnostic errors; therefore elaboration of unique criteria for histological evaluation is a problem of great importance. HGSIL should be differentiated with regenerative and atrophic processes in the cervix uteri with a special accuracy.
