|
|
Mucosa of vagina is lined by _____ epithelium |
non-keratinizing stratified squamous epithelium |
|
where in the vagina are the cells derived from the urogenital sinus? |
lower 1/3 - stratified squamous;
- grow upward to replace the columnar epithelium lining of the upper 2/3 of the vagina (derived from the Miillerian ducts).
|
|
Increased incidence of adenosis in females |
who were exposed to diethylstilbestrol (DES) in utero |
|
why is adenosis important? |
can lead to clear cell adenocarcinoma |
|
adenosis |
Focal persistence of columnar epithelium in the upper 2/3 of the vagina |

CLEAR CELL ADENOCARCINOMA |
|
complications of exposure to DES in utero |
1. Adenosis --> CLEAR CELL ADENOCARCINOMA 2. improper smooth muscle formation in GU canal --> ectopic pregnancies, other complications |

|
grape-1 ike mass protruding from the vagina or penis |
EMBRYONAL RHABDOMYOSARCOMA |
|
EMBRYONAL RHABDOMYOSARCOMA |
Malignant mesenchymal proliferation of immature skeletal muscle; rare |
|
what kind of cells is EMBRYONAL RHABDOMYOSARCOMA made of? |
Rhabdomyoblasts, the characteristic cell, exhibits cytoplasmic cross-striations (like an immature muscle cell would) and positive immunohistochemical staining for desmin and myogenin. |
|
tumor positive immunohistochemical staining for desmin and myogenin. |
EMBRYONAL RHABDOMYOSARCOMA desmin - muscle cell myogenin - nuclear transcription factor that would be present in immature muscle cells |
|
When spread to regional lymph nodes occurs, cancer from the lower 1/3 ofvagina goes to, |
inguinal nodes |
|
When spread to regional lymph nodes occurs, cancer from the upper 2/3 goes to |
regional iliac nodes |
|
Exocervix is lined by , |
nonkeratinizing squamous epithelium |
|
Endocervix is lined by |
a single layer of columnar cells. |
|
can you get condyloma in the cervix? |
yes, HPV infection can affect vulva, vagina, cervix |
|
where does HPV like to especially invade? |
|
|
if you get infected with HPV, what are the chances that it will be a persistent infection? |
10%
(90% of infection are cleared by the immune system and have no risk of going to CIN) |
|
which genes in HPV make them more likely to cause CIN? |
E6 and E7 proteins which result in increased destruction of p53 and Rb, respectively
E6 - p53 E7 - Rb
(normally, if there is too much damage to the cell, p53 calls in Bax, which deactivates bcl2; without bcl2, the mitochondrial membrane no longer stable --> releases cytC, which activates apoptosis. Stops G1->S phase
Rb: Rb holds E2F, which is needed for progression through cell cycle. Need to phosphorylate Rb before it will release E2F. If no Rb, E2F freely available, helps cell move through cell cycle) |
|
is CIN neoplasia ? |
no, it's dysplasia |
|
what's the difference between CIN I and carcinoma in situ of cervix? |
CIN I-III could potentially reverse (because it's a dysplasia) Carcinoma in situ (CIS) will not reverse
CIN I - 66% potential to reverse CIN II - 33% potential to reverse |
|
next step after CIS |

cervical carcinoma presents as |
Presents as vaginal bleeding, especially postcoital bleeding, or cervical discharge |
