Cervical erosion

Cervical erosion refers to ectopic cervical columnar epithelium, and is not a true erosion. When the epidermis of the outer mouth of the cervix is ​​replaced by another type of epithelial tissue of the cervix, due to the thin new epithelium that meets the coverage, you can even see the underlying blood vessels and red tissue, which looks like erosion, which is a part of cervical physiological changes. First, it is not a pathological change. The erroneous name of "cervical erosion" has been "cancelled" in the 2008 textbook of medical obstetrics and gynecology and obstetrics, replaced by the "cervical columnar epithelial ectopic" physiological phenomenon. Physiological cervical columnar epithelium is more common in adolescents, women of childbearing age with strong estrogen secretion, oral contraceptives or during pregnancy. Due to the action of estrogen, the scale junction is shifted outwards, and the appearance of the cervix is ​​erosion-like.
