25
what age group is endometriosis seen in?
20s and 30s
26
what is a complication of endometriosis?
can invade and spread through wall of bowel....leads to pain on deification
27
what are the four theories of endometriosis?
regurgitation theory metaplastic theory benign metastasis theory extra uterine stem/progenitor theory
28
explain the regurgitation theory
retrograde menstruation thru fallopian tube
29
explain the metaplastic theory
endometrium comes from the mesothelium of the pelvis/abdomen | mesonephric remnants can differentiate into EM
30
explain benign metastasis theory
endometrium issue can spread thru the blood and lymphatics to distant site
31
explain the extra uterine stem/progenitor cell theory
bone marrow cells differentiate into endometrium tissue
32
Can men treated with high dose estrogens get endometriosis?
yes
33
What is the new molecular theory of endometriosis?
1. please of pro inflammatory factors (PGE2!!,IL1-B, TNF-alpha) 2. these pro inflammatory factors increase the # of estrogen receptors 3. Estrogen increases the survival of EM tissue
34
how do you treat endometriosis?
treat with aromatase inhibitors
35
what factors into the progression of endometriosis?
increased vascular networks decreased immune clearance increased response to ER and decreased response to PR
36
what is the association of endometriosis and cancer?
endometriorid and clear cell have high associations with cancer
37
what mutations are seen with endometriosis?
mutations in PTEN | AND ARID1A
38
Whats a DD of endometriosis?
endosalpingosis (fallopian tube tissues are seen outside of the fallopian tube) only if glands are seen
39
What is the precursor to EM carcinoma in the uterus?
EM hyperplasia atypical
40
what are the clinical signs and symptoms of endometriosis?
``` sever dysmenorrhea dyspareunia pelvic pain menstrual irregularities infertility ```
41
What is adenomyosis?
endometrial tissue with the myometrium
42
what is the clinical presentation of adenomyosis?
menometrorrhagia (irregular and heavy periods) colicky pain dyspareunia and pelvic pain
43
what is the micro view of adenomyosis?
next of endometrium separated from the basalts by 2-3 mm
44
what can cause endometrium polyps?
tamoxifen
45
where do you see atrophic EM polyps?
post menopausal women
46
what is EM hyperplasia
increased proliferation of glands vs stroma
47
how is EM hyperplasia caused?
-by prolonged estrogenic stimulation of EM unopposed by progesterone -anovulation -obesity -incr estrogen production -menopause -granulosa cell tumors of the ovary ovarian cortical stromal hyperplasia
48
What is the molecular basis behind EM hyperplasia?
inactivation of PTEN
49
what does PTEN do?
encodes lipid phosphatase and neg regulator of PI3K-AKT pathway
50
what is cowed syndrome
gremline mutation in PTEN | which causes increased EM carcinoma and great cancer
51
what is another name for atypical hyperplasia of the endometrium?
Endometrial intraepithelial neoplasia EIN
52
does non atypical EM hyperplasia progress to adenocarcinoma?
no | but can evolve into cystic atrophy when ER is withdrawn
53
what pattern of proflierating glands does atypical EM hyperplasia (EIN) have
complex pattern of proliferating glands with nuclear atypic and back to back glands
54
how to treat atypical hyperplasia?
hysterectomy if it is a young women-trial of progestin therapy with close follow up...if it doesn't regress after having a child..remove uterus
55
what is the most common carcinoma of the female genital tract
cancer of the endometrium
56
when do you see endometrial cancer?
post menopausal
57
what is a sign of endometrial cancer?
post menopausal bleeding or irregular bleeding with leukorrhea
58
whats the difference between normal EM cancer and serous EM cancer?
serous EM cancer spread through tube and lymphatics... | extrauterine spread
59
what population is serous EM usually seen?
african american women
60
what are the new treatment hopes for EM cancer?
Inhibiting PI3K/AKT pathway
61
what is the most common type of EM carcinoma?
