What is cervical columnar ectopia grade 3?

Cervical erosion is the most common gynecological disease, but now the term cervical erosion has been replaced by the physiological phenomenon of "cervical columnar epithelium ectopia", so cervical columnar epithelium ectopia is what we often hear about cervical erosion. Cervical columnar epithelial ectopia grade 3 is the most serious degree of cervical erosion and must be treated in time!

What is cervical columnar ectopia grade 3?

Grade 3 cervical erosion is the most serious degree of cervical erosion, and the erosion area has exceeded 2/3 of the surface of the cervix; Grade 3 cervical erosion greatly increases the risk of infertility and cancer. Cervical erosion is caused by the stimulation of inflammatory secretions, which causes the squamous epithelial cells of the mucosa of the external opening of the cervical canal to fall off and be covered by proliferating columnar epithelium. The surface is bright red and smooth or uneven. This change is called "cervical erosion". Due to different degrees of inflammatory stimulation, the columnar epithelium of the cervical mucosa grows slowly, and the epithelium is flat and smooth in appearance, which is simple erosion; when the columnar epithelium grows quickly and forms glandular hyperplasia, it is adenoid erosion. If the glands are dilated, it may be a follicular erosion accompanied by stromal hyperplasia, forming small protrusions, and if the covering is uneven columnar epithelium, it will form a papillary erosion. Cervical erosion is one of the most common gynecological diseases.

Grading standards:

1. Mild erosion: The erosion area accounts for less than 1/3 of the entire cervical area;

2. Moderate erosion: The erosion area accounts for 1/3 to 2/3 of the entire cervical area;

3. Severe erosion (cervical erosion degree 3): The erosion area occupies more than 2/3 of the entire cervical area.

Causes of cervical columnar epithelium ectopia 3 degree:

In chronic cervical erosion, the squamous epithelium covering the surface of the vaginal part of the cervix necrotizes and detaches, forming a superficial defect, which is called true erosion, which is rare. The common cervical erosion in clinical practice actually refers to the proliferation of the columnar epithelium of the cervical canal mucosa after previous epithelial damage, which extends to the defect of the leucocyte epithelium in the uterine vaginal part, covering the wound surface and replacing the original leucocyte epithelium defect area. Because the columnar epithelium is thin, the congested capillaries under the mucosa are obvious and visible, so the diseased mucosa of the external cervical os appears as a bright red erosion-like area to the naked eye.

"Cervical columnar epithelium ectopia": There are two types of epithelium on the surface of the female cervix during the embryogenesis period, primitive squamous epithelium and columnar epithelium. The squamous epithelium is multi-layered, some have seven or eight layers, some have more than ten layers, and looks very smooth; the columnar epithelium is single-layered and relatively thin, and the blood vessels under the epithelium can be seen through the epithelium. They are like strawberries squeezed together, which is also a physiological structure. Normally, the columnar epithelium is located inside the cervical canal and cannot be seen by the naked eye. Under the action of estrogen, such as during puberty, the volume of the cervix grows rapidly and greatly exceeds the uterine body, exposing the cervical columnar epithelium at the external os of the cervix, which appears red and rough. This is not really 'erosion', but a normal 'stress' response that occurs when hormones surge in women's bodies. ”
