Causes of chronic cervicitis
It is a common disease of women in childbearing period. It is mostly caused by cervical laceration caused by childbirth, abortion or surgery, and bacterial infection. Because the cervical epithelium is thin, there are many folds and glands, the pathogens are not easy to be completely hidden, and chronic inflammation is easy to form.
Pathological types of chronic cervicitis
Most common. The squamous epithelium on the surface of the cervix falls off and is covered by the columnar epithelium of the cervical canal. Because the columnar epithelium is thin and the subcutaneous blood vessels are exposed, it is red, which is called erosion. Among them, with pathological development:
(1) Simple type: a single layer of columnar epithelial hyperplasia, the epithelium is flat, and the surface is smooth and bright red.
(2) Granular type: columnar epithelial hyperplasia with interstitial hyperplasia and uneven surface.
(3) Mastoid type: columnar epithelium and interstitial hyperplasia are too long, and the surface is rough and uneven.
2. Cervical hypertrophy
The cervix was hypertrophic to varying degrees, hardened, and smooth.
3. Cervical polyps
Single or multiple polyps, less than 1 cm in diameter, are small cherry-like or tongue-like, have fine pedicles, bright red, soft and brittle, easy to bleed, slender and connected to the cervix.
4. Cervical gland cyst
Small vesicles of varying sizes and protrusions are formed on the surface of the cervix, which are blue-white and contain colorless mucus.
