Cervical erosion can be divided into many types according to different properties.

Cervical erosion can be divided into many types according to different properties.

1. Classification according to the manifestation of erosion surface

Simple erosion: The epidermis is relatively flat and smooth, and the eroded surface is mostly covered by a single layer of columnar epithelium. It is generally common in the early stages of inflammation.

Granular erosion: The surface is uneven and granular in appearance. Inflammation persists, causing excessive proliferation of the cervical epithelium.

Papillary erosion: Due to the obvious proliferation of glandular epithelium and its stroma, the unevenness of the surface will be more obvious, and the appearance will be papillary-like.

2. Classification according to different causes of disease

Specific erosion: generally caused by bacterial infection, common pathogens include gonococci, Chlamydia trachomatis, etc.

Non-specific erosion: mostly caused by imbalance in estrogen secretion, common in unmarried or childless women.

3. Classification according to the severity of the disease

Pseudoerosion: It is mostly a red area around the external cervical opening. During colposcopy, after applying 3% acetic acid on the surface of the red area, it can be seen that the red area has a local "grape cluster" change, which is called "exfoliation of the surface epithelium" in pathology.

True erosion: It is only a short stage in the pathological process and will eventually be covered by columnar epithelium and become pseudoerosion.

4. Classification according to the degree of erosion area

Mild cervical erosion: The lesion area occupies less than one third of the entire cervical area.

Moderate cervical erosion: The lesion area occupies less than two-thirds of the entire cervical area.

Severe cervical erosion: The lesion area occupies more than two-thirds of the entire cervical area.
