A nabothian cyst (or nabothian follicle) [1] is a mucus-filled cyst on the surface of the cervix. They are most often caused when stratified squamous epithelium of the ectocervix (portion nearest to the vagina) grows over the simple columnar epithelium of the endocervix (portion nearest to the uterus). This tissue growth can block the cervical ...
After menopause, the uterine structures involute and the functional squamocolumnar junction moves into the cervical canal. [17]: 41 Nabothian cysts (or Nabothian follicles) form in the transformation zone where the lining of metaplastic epithelium has replaced mucous epithelium and caused a strangulation of the outlet of some of the mucous glands.
Cervical stenosis may be present from birth or may be caused by other factors: Surgical procedures performed on the cervix such as colposcopy, cone biopsy, or a cryosurgery procedure [3] Trauma to the cervix [3] Repeated vaginal infections [3] Atrophy of the cervix after menopause [3] Cervical cancer [1] Radiation [1] Cervical nabothian cysts
On occasion an ovarian cyst can rupture and give rise to internal hemorrhage. This may occur during ovulation or as a result of endometriosis . If the pregnancy test is positive, consider pregnancy related bleeding (see obstetrical hemorrhage ), including miscarriage and ectopic pregnancy .
Sim subsequently developed another procedure that did not require the full-thickness dissection of the vaginal wall. In 1888, another method of treating anterior vaginal wall Manchester combined an anterior vaginal wall repair with an amputation of the cervix and a perineorrhaphy. In 1909, White noted the high rate of recurrence of cystocele ...
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
A tunnel cluster, more formally tunnel cluster of the cervix and cervical tunnel cluster, is a benign group of dilated endocervical glands in the cervix. It is significant only in that it can be confused for a malignancy, i.e. cancer .
