Ectropium (gynecology)

A change in the epithelium of the mucous membrane of the cervix, in which there is an eversion of the epithelium of the endocervix (single-layered columnar epithelium) into the region of the exocervix (squamous epithelium). The acidic vaginal environment disrupts the area of ​​the less resistant cylindrical epithelium, thereby causing erosive and inflammatory processes. Prolonged exposure to an acidic environment leads to the formation of a transformation zone (squamous cell metaplasia), which is also the area with the most frequent occurrence of dysplastic changes.

During colposcopy, we observe deep red areas with a tendency to light bleeding. Ectropion can be caused by hormonal changes, inflammation or trauma (eg after childbirth). These lesions can easily be mistaken for a tumor process. The finding of ectropion is physiological in multiparous. In the case of nulliparous women, we are talking about ectopia.
