Cervical ectropion (or cervical eversion) is a condition in which the central (endocervical) columnar epithelium protrudes out through the external os of the cervix and onto the vaginal portion of the cervix undergoes squamous metaplasia and transforms to stratified squamous epithelium. Although not an abnormality it is indistinguishable from early cervical cancer; therefore further diagnostic studies (e.g. Pap smear biopsy) must be performed for a differential diagnosis.
