What causes this condition to develop? Some women are even born with it. It can also be due to hormonal fluctuations. This includes teenagers, pregnant women, and women who use birth control pills or patches that contain estrogen. Cervical ectropion is rare in postmenopausal women.

Yosar The eversion of the columnar epithelium is more pronounced on the anterior and posterior lips of the ectocervix and less on the lateral lips.
Thus the original squamocolumnar junction is located on the ectocervix, far away from the external os Figures cervjcal. Not to be confused with Ectropion. Cervical ectropion Thus, it is a variant of intrauterine squamous metaplasia, in which differentiation of the squamous epithelium is not fully completed due to an interference with normal maturation. If the epithelialization proceeds normally, the original squamocolumnar junction will be located at the external os cerfical birth.
The cervix is covered by both stratified non-keratinizing squamous and columnar epithelium. However, a study found that women under 30 with cervical ectropion had a higher rate of chlamydial infection than those who did not. A color-coded guide to vaginal discharge How to stop or speed up your period What do different types of vaginal discharge mean?
This includes teenagers, pregnant women, and women who use birth control pills or patches that contain estrogen. It may be found incidentally when a vaginal examination or pap smear test is done. Date due for review: Cauterization usually resolves these symptoms.
Development of squamous metaplastic epithelium a The arrows indicate the appearance of the evesion reserve cells. Certain oncogenic human papillomavirus HPV types may persistently infect the immature basal squamous metaplastic cells and transform them into atypical cells with nuclear and cytoplasmic abnormalities. A recent study tries to pin down the exact molecules involved.
A schematic diagram of further glandulqr of immature squamous metaplasia. If no author information is provided, the source is cited instead. The first option uses an electric current diathermy to cauterise the top layer of the cervix. This can be accomplished using heat diathermycold cryosurgeryor silver nitrate. This is called cautery. The area on the outside of the cervix where glandular cells come into contact with squamous epithelial cells is called the transformation zone or the stratified squamous epithelium.

Squamous metaplasia in the cervix refers to the physiological replacement of the everted columnar epithelium on the ectocervix by a newly formed squamous epithelium from the subcolumnar reserve cells.
This chapter deals with the gross and microscopic anatomy of the uterine cervix and the physiology of the transformation zone. In premenopausal women, the original squamous epithelium is pinkish in colour, whereas the newly formed metaplastic squamous epithelium looks somewhat everaion on visual examination. It also considers how it differs from cervical cancer and chlamydia. Cervical ectropion is not caused by cancer and is not an early symptom of cervical cancer.
The basal cells divide and mature to form the next few layers of cells called parabasal cells, which also have relatively large dark-staining eversioon and greenish-blue basophilic cytoplasm.
It usually begins as a localized enlargement of a single columnar papilla and appears as a mass as it enlarges. When you click on an answer below, your evdrsion will be submitted automatically. The physiological replacement of the everted columnar epithelium by a newly formed squamous epithelium is called squamous metaplasia.
Identifying the transformation zone is of great importance in colposcopy, as almost all manifestations of cervical carcinogenesis occur in this zone. The supravaginal portion meets with the muscular body of the uterus at the internal cervical os. The cervix, the lower fibromuscular portion of the uterus, measures cm in length and 2.
It appears as a large reddish area on the ectocervix surrounding the external os Figures 1. Gross anatomy of the u They produce mucus and bleed easily, which may lead to spotting and pain during or after sexual activity.
From the perimenopausal period and after the onset of menopause, the cervix shrinks due the lack of vervical, and consequently, the movement of the new squamocolumnar junction towards the external os and into the endocervical canal is accelerated Figures 1.

What Is Cervical Ectropion (Cervical Erosion)?
Causes[ edit ] Cervical ectropion is a normal phenomenon, especially in the ovulatory phase in younger women, during pregnancy, and in women taking oral contraceptive , which increases the total estrogen level in the body. Mucopurulent cervicitis may increase the size of the cervical ectropion. As estrogen levels rise during puberty, the cervical os opens, exposing the endocervical columnar epithelium onto the ectocervix. This area of columnar cells on the ectocervix forms an area that is red and raw in appearance called an ectropion cervical erosion. It is then exposed to the acidic environment of the vagina and, through a process of squamous metaplasia , transforms into stratified squamous epithelium.
