Portioectopy

from Wikipedia, the free encyclopedia

As Portioektopie refers to a spread of the epithelium from the cervical canal to the area of the external os ( portio vaginalis uteri ). It arises during sexual maturity or through external hormone intake. The ectopic epithelium looks reddish and fine black due to the good blood circulation. Due to external factors such as the acidic vaginal environment , infections or mechanical irritation, the columnar epithelium is replaced by squamous epithelium, which looks gray. This growing either vaginalis from the edge of the cervix forth across the epithelium or produced by transformation of reserve cells of the epithelium.

If gland ducts are obstructed through the squamous epithelium, mucous retention cysts ( ovula nabothi ) can develop.
