| cervical ulceration | A partial or complete absence of the mucosa which normally covers the cervix. These lesions or ulcers, may occur as the result of trauma (for example intercourse, tampon insertion), infection or chemicals (for example spermicidal creams or foams, douches). There appears to be a increased risk of cervical erosion with vaginal use of chemical agents or those with multiple sex partners. Symptoms of cervical erosion include vaginal bleeding and post-coital bleeding. Often there may be no symptoms at all. Erosions or ulcerations of the cervix are generally noted on the pelvic examination and can be an indicator of cervical cancer. For this reason a PAP smear will be recommended. most cervical erosions will heal spontaneously without intervention. (27 Sep 1997) |
