Cervical polyps are a pathological change of chronic inflammation of the cervix and are very common in clinical practice. Under normal circumstances, the cervix has a variety of defense functions, but the cervix is susceptible to damage from childbirth, abortion or surgery, and the single-layer columnar epithelium of the cervical canal is relatively poor in its ability to resist infection. Moreover, due to the large number of folds in the mucous membrane of the cervical canal, it is very difficult to remove the pathogens completely in the event of infection, which leads to chronic inflammation of the cervix. The pathogens of chronic inflammation mainly include staphylococcus, streptococcus, Escherichia coli and anaerobic bacteria, and chronic cervicitis caused by Chlamydia trachomatis and Neisseria gonorrhoeae infections is also increasing. Chronic inflammation long-term stimulation of the cervical canal local mucosal hyperplasia, the uterus has a tendency to exclude foreign bodies, so that the proliferation of mucosa gradually from the base to the cervical external opening protruding and the formation of polyps, one or more varying, the diameter of the general about 1cm, color red, tongue-shaped, soft and brittle, easy to bleed, the tip of the elongated. The root is mostly attached to the external cervical os, and a few in the wall of the cervical canal. Light microscopy polyp center for connective tissue with congestion, edema and inflammatory cell infiltration, the surface is covered with a layer of high columnar epithelium, and the cervical canal epithelium is the same. Cervical polyps are caused by inflammation and may grow larger and larger. If larger cervical polyps are found, they should be removed as soon as possible.
