The cervix is covered with a layer of skin-like cells on its outer surface, called the ectocervix
. The results of your cervical screening are based on the analysis of the cells from the surface of the ectocervix
Previous reports indicate that giant cervical polyps originate more often from the ectocervix
and rarely from the endocervix in contrast to the commonly seen cervical polyps.
(8,17,18) It is related to the more intense sexual activity in this age (that favors the infection) as well as to an anatomical characteristic of the young women (cervical ectopy) that exposes the columnar epithelium in the ectocervix
, making it more vulnerable to pathogen infections.
Furthermore the transformation zone (the interface between the squamous ectocervix
and columnar endocervical canal) is thought to be particularly susceptible to HIV infection as it has an enhanced population of [CD4.sup.+] T cells [55, 67].
There are also intraepithelial lymphocytes (IELs) in the ectocervix
and the transformation zone (TZ) which are mostly CD8+ and less frequently CD4+ (31,32).
"This extension of the single-layered columnar epithelium onto the ectocervix
may facilitate genital tract shedding," the researchers said.
A ringed forceps was used to gently peel back the cervical eschar from the most distal ectocervix
toward the os in a radial manner.
In these patients the tumors were developing on the ectocervix
, rather than in the endocervical canal.
On the contrary, the bacteria reaching the ectocervix
must compete for resources and be compatible with the metabolic wastes from the normal flora of the vagina.
In this case, visualization of the ectocervix
must first be maximized.
The scanning, which involves the entire ectocervix
and takes 12 seconds, follows application of 3%-5% acetic acid to the cervix.
The physician used 2 Dacron swabs: one directed at the endocervix and the other at the ectocervix
. Each swab was placed in specimen transport medium (STM) in a separate standard Hybrid Capture collection tube.
