Category: cervical erosion typing typing under different circumstances are different . Generally have the following typing methods :
1 , according to the size of clinical erosion cervical erosion can be divided into light (I), in (II), weight (III) three degrees .
Ⅰ cervical erosion is the erosion area less than the entire cervical area of 1 /3, also known as mild cervical erosion.
Ⅱ degree of cervical erosion is when the erosion area accounts for between 1 /3 to 2 /3 of the cervical area , also known as moderate cervical erosion.
Ⅲ degree of cervical erosion cervical erosion refers to the cervical area occupies the entire area of 2/3 or more, also known as severe cervical erosion .
2 , can be based on the performance of cervical erosion cervical erosion will be divided into three types:
Simple cervical erosion : more common in early inflammation , erosion surface is covered with a single layer of columnar epithelium , the skin is relatively flat and smooth ;
Particle type of cervical erosion : inflammation persists, make cervical epithelial hyperplasia , erosion surface is uneven , grainy appearance .
Papillary cervical erosion : If glandular epithelium and stromal hyperplasia significantly uneven phenomenon is more pronounced , papillary , namely papillary erosion.
3, according to the etiology of cervical erosion can be divided into two specific and non-specific .
Specificity : refers to infection caused by the bacteria . Neisseria gonorrhoeae and Chlamydia trachomatis cervical infection is the most common pathogen .
Nonspecific : Most estrogen secreted by the imbalance . For example, many unmarried people who have not given birth .
4 , depending on their disease process will be divided into the following types of cervical erosion .
Pseudo-erosion : erosion of the concept of pathology is the ldquo; surface epithelial shedding rdquo;, while common in clinical cervical erosion , mostly red area around the mouth of the cervix . Colposcopy , coated in the red zone after 3% acetic acid , can be seen in the red zone was partially ldquo; grapes rdquo; change , which was caused by columnar epithelial edema . If the biopsy of the line , can be seen under a microscope, the surface coating columnar epithelium . Therefore, as defined in strict accordance with pathology erosion , erosion does not belong here , it was suggested that called pseudo- erosion. Seen in clinical practice cervical erosion , mostly this .
True erosion : As surface of the cervix often have more mucus or purulent discharge cover long-term stimulation of these secretions , dipping cervical squamous epithelium around the mouth , coupled with the inflammatory infiltrate deep cervical tissue , so covering the cervix surface squamous lose its vitality and loss, ulcers , and this is true erosion . But this erosion surface was quickly covered the surrounding columnar epithelium, forming a granular surface , there are some shiny red zone , that pseudo- erosion. Our daily work found cervical erosion , mostly pseudo-erosion , and true erosion of the lesion in only a short stage, the outcome will be the surface is covered with columnar epithelium and become pseudo- erosion.
5 , exclude mechanical damage , infection and other reasons, divided into congenital and acquired erosion erosion .
Congenital erosion : In late pregnancy , maternal influence columnar epithelium by estrogen , cervical mucous columnar epithelial hyperplasia, cervix begin to grow outward and beyond the cervix, mouth , so the newborn baby girl about 1 /3 of the cervix looks like adult cervical erosion. Since this time there is no laceration , infection factors such as the formation of cervical erosion , so put this erosion is called congenital erosion. Effects of estrogen from the mother after birth and gradually subsided, newborn baby girl this erosion is also self-limiting.
Acquired erosion : erosion is acquired and congenital erosion contrast, multi- functional ovarian strong women of childbearing age , cervical columnar epithelial ovarian estrogen produced by the emergence of hyperplasia, over the cervix, mouth , making erosion of the cervix, mouth was like . Such erosion and erosion caused by inflammation look the same, but the reasons for the erosion caused by the different.
