What are the types of cervical erosion?

According to different situations of cervical erosion, it can be divided into many types, including the following aspects:

1. Classification based on erosion area

It can be divided into three categories: I (mild), II (moderate), and III (severe). When the erosion area accounts for 1/3 of the total area of ​​the cervix, it is mild cervical erosion, and the patient is generally asymptomatic and easy to treat; when the erosion area accounts for 1/3 to 2/3 of the total area of ​​the cervix, it is called moderate cervical erosion, which is between mild and severe erosion, and the patient will have symptoms such as increased and sticky vaginal discharge; when the erosion area exceeds 2/3 of the total area of ​​the cervix, it is called severe cervical erosion, and if not treated in time, it may become cancerous.

2. Classification based on the manifestation of erosion

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

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

Papillary erosion: The glandular epithelium and stroma proliferate significantly, the unevenness is more obvious, and it is papillary-shaped.

3. Classification based on etiology

According to the etiology, cervical erosion can be divided into specific and nonspecific types. Among them, specific cervical erosion is caused by bacterial infection, the main pathogens are gonococci and Chlamydia trachomatis. Nonspecific cervical erosion is mostly caused by unbalanced estrogen secretion, which is more common in unmarried women without children.
