Pathological manifestations of cervical erosion

Cervical erosion is abbreviated as cervical erosion. It is a normal physiological phenomenon, not a disease. The term cervical erosion has been cancelled abroad, and foreign countries generally do not treat mild inflammation, only do cytological screening, and take corresponding treatment according to the cytological results. In recent years, domestic textbooks have also been revised to cancel the name of "cervical erosion" and replace it with the physiological phenomenon of "cervical columnar epithelium ectopia".

Cervical columnar epithelium ectopia: There are two types of epithelium on the surface of the female cervix during embryogenesis, primitive squamous epithelium and columnar epithelium. The squamous epithelium is multi-layered 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.

However, it should be noted that cervical erosion can also be a manifestation of certain diseases such as chronic cervicitis. Patients often have increased secretions, contact bleeding, infection, etc., which should be paid attention to. At this time, the changes in the cervix are pathological changes, and the pathological manifestations are: after the previous epithelial injury, the columnar epithelium of the cervical canal mucosa proliferates and extends to the defect of the sphingoid epithelium of the vaginal part of the uterus, covering the wound surface and replacing the area of ​​the original sphingoid epithelium defect. Because the columnar epithelium is thin, the congested capillaries under the mucosa are obvious, so the lesions of the mucosa of the external cervical opening appear as bright red erosion-like areas. In true erosion, the squamous epithelium covering the surface of the vaginal part of the cervix necrotizes and detaches, forming a superficial defect.
