Exam 2 Review Flashcards
What are the general features of endometriosis?
- Endometrial tissue that forms TUMOR-LIKE NODULES (foci) outside the uterus.
- Foci composed of endometrial glands & stroma. (these glands respond to estrogenic stimulation & proliferate with the normal endometrium)
Note:
Ovarian endometriosis may present w/ large cystic lesions. The cysts are filled w/ red-brown fluid derived from decomposed blood = Chocolate Cyst.
Where are the common locations of Endometriosis?
OVARY, fallopian tube or on the pelvic peritoneum, but occasionally it may be found outside the pelvis, even on the umbilicus, appendix, and colon.
–Other locations (from pic): pouch of Douglas, vulva, bladder, abdomen
Who is more likely to get Endometriosis?
-20s-30s & 30-40
A disease of women of reproductive life (3rd and 4th decades)
- Women of higher socioeconomic groups
What is the most popular theory for the pathogenesis of Endometriosis?
- Endometrial tissue is regurgitated during normal menstruation & instead of entering vagina, it is transferred upstream, it enters abdominal cavity thru fallopian tubes. The glands implant on the serosa of ovary or peritoneum.
- Forms typical red-brown nodules or plaques. Most foci of endometriosis are located close to orifice of fallopian tubes which support this theory.
What are Leiomyomas (fibroids)?
-What % is benign/ malignant?
Benign tumors originating from the smooth muscle cells of the myometrium.
-98% are benign (leiomyomas), 1-2% are malignant (leiomyosarcomas)
Which tumors are the most common uterine tumors?
- Leiomyomas
- ~ 20% of all women of reproductive age have them (under influence of Estrogen, more common in African Americans).
- They are small & clinically inapparent.
What are the 3 types of uterine fibroids?
1) Intramural: embedded within the myometrium
2) Subserosal: Occurs beneath covering serosa of the uterus
3) Submucosa: protrude into the endometrial cavity
* Associated w/ increase risk of miscarriage/infertility b/c decreases ability to implant into uterus
-What are the Risk factors for endometrial adenocarcinoma ?
1) Are taking exogenous estrogen in the form of pills or injections.
2) Have estrogen-producing tumors
3) Obese & form estrogen at an increased rate by fat tissue conversion.
- -DM (diabetes) and HTN (hypertension).
4) Are nulliparous or have early menarche & late menopause (related to longer exposure to estrogen)
What can reduce the risk of endometrial carcinoma, why?
- Multiple pregnancies reduce because progesterone, (dominant pregnancy hormone) gives the endometrium long breaks from proliferation.
- Estrogens stimulates proliferation of endometrial glands, (hyperplasias) which undergo malignant transformation.
Why does the beneficial risks of ESTROGEN outweigh the risks for carcinoma?
- B/c endometrial cancer is detected early & treatment is successful.
- “80% of all endometrial cancers are detected while the tumor is confined to the uterus, and affected women have an excellent prognosis.”
What is endometrial hyperplasia ?
-Caused by excessive Estrogenic stimulation of endometrium leading to cystic expansion & thickening of the entire endometrium w/ multi-layering of the endometrial glands with scant endometrial stroma.”
What are the 3 types of endometrial hyperplasia & percentages?
1) Simple Hyperplasia:
- When there is minimal glandular complexity and no cytologic atypia.
- (1% progression to carcinoma)
2) Complex Hyperplasia:
- When there is multilayering of the glands (complexity) w/ crowding, but still NO cytologic atypia.
- (3% may develop adenocarcinoma)
3) Atypical Hyperplasia:
Complexity to glands w/ crowding & there is cytologic atypia. The epi. cells are enlarged & hyperchromatic w/ high N/C.
-(25% of these cases progress to adenocarcinoma)
- What type of cancer is endometrial adenocarcinoma?
- where does it originate from?
- Most common malignant tumor of female genital tract. (50% of GYN malignancies)
- Disease of older women (35 yo+)
- Arises from epithelial cells lining the endometrial glands.
- Tumor appears as fungating mass protruding into uterine lumen. The tissue is “friable” & soft b/c it consists of atypical glands w/ little tissue stroma.
What are the SYMPTOMS of endometrial adenocarcinoma?
What is TX?
-Most common symptoms: Vaginal bleeding that is spotting between 2 menstruations or as prolonged pronounced menstual bleeding (menorrhagia)
TX:
- D&C (dilate cervix and scrape endometrium), -TAH-BSO (hysterectomy w/ or w/o ovaries),
- lymph node removal of metastases
- Radiation for advanced pt’s
- Chemo for inoperable cases
-General features of ectopic pregnancy.
- Implantation of the fetus in any other site than normal uterine location.
- Most commonly the ovary, abdominal cavity & 95% occurring in fallopian tubes
- The fertile zygote undergoes normal development w/ formation of placental tissue & amniotic sac.
- Placenta poorly attached to wall of the tube, weakens it w/ the possibility of rupture & intraperitoneal hemorrhage.
-
Signs and Symptoms of Ectopic Pregnancy?
Signs/Symptoms:
- Severe abdominal pain w/ rupture & possibility of shock w/ signs of an acute abdomen.
- Pregnancy tests are positive
*****Aspiration of “fresh blood” from the pouch of Douglas (POSTERIOR FORNIX) denotes rupture.
What is helpful in the diagnosis of Ectopic Pregnancy?
- An endometrial biopsy is helpful in diagnosis.
- Absence of chorionic villi is consistent b/c villi are in the tube
- Biopsy will show a decidual reaction of endometrium
***Ultrasound will show dilation of the fallopian tube.
- ____________ pregnancies are ectopic ?
- Rapture occurs ________ after pregnancy.
-1/150
(1/400 die)
-2-6 weeks
-What is the most common cause of ectopic pregnancy ?
***Most common pathologic condition leading to ectopics is chronic salpingitis.
-Other factors: peritubal adhesions as from endometriosis, previous surgeries & leiomyomas.
The intratubal adhesion forms a barrier to normal passage of the zygote, so implants at the site of obstruction.
What are the two MOST common complications of chronic salpingitis from PID ?
1) Sterility (infertility): Risk rs increases w/ each Gonococcus infection, & caused by scarring of fallopian tubes, (occludes the lumen and prevents sperm from reaching the ovulated egg.)
2) Ectopic pregnancy: Increase w/ previous salpingitis.
Most common site for Ectopic being the fallopian tubes
- Abscesses: may develop in the fallopian tubes, ovaries, or peritoneum
- Peritonitis: bacteria may spread from ovaries & fallopian tubes.
Which female reproductive tract cancers are adenocarcinoma ?
-Tissues that are glandular = adenocarcinoma
***Uterus, Fallopian Tubes, & Ovaries are glandular so #1 cancer=adenocarcinomas
- Endometrial Hyperplasia (Non-neo. Uter.)
- Endometrial Polyps (Non-neo. Uter.)
- Endometrial Adenocarcinoma (Neo. Uter.)
- Tumors of fallopian tubes
- Tumors of surface epithelium (Neo. Ovar.)
- Serous Cystadenocarinoma
- Solid Serous Cystadenocarcinoma
- Mucinous Cystadenocarcinoma
Which female reproductive tract cancers are squamous cell?
-Tissues that squamous = squamous cell carcinoma
***Vulva, Vagina, & Cervix are squamous epithelium so #1 cancer=squamous cell carcinomas
*Pyometria (Non-neo. Uter.)
Endometrial Hyperplasia (Non-neo. Uterus)
adenocarcinoma or squamous cell carcinomas?
***adenocarcinoma
Caused by excessive estrogenic stimulation of the endometrium leading to cystic expansion of the entire endometrium with focal branching of the glands with scant endometrial stroma.
- When there is minimal glandular complexity & no cytologic atypia, simple hyperplasia (1% progress to carcinoma)
- When there is multilayering of the glands (complexity) with crowding, complex hyperplasia (3% may develop adenocarcinoma)
- Atypical hyperplasia is when there is complexity to the glands with crowding and there is cytologic atypia. The epithelial cells are enlarged and hyperchromatic with high N/C ratios and prominent nucleoli.
- Endometrial Polyps (Non-neo. Uterus.)
- adenocarcinoma or squamous cell carcinomas?
- *adenocarcinoma
- Benign, localized overgrowths that project from the endometrial surface into the endometrial cavity
- Most arise in the fundus, usually solitary, and vary in size
- Not believed to be pre-neoplastic, but up to 0.5% harbor adenocarcinomas.
- Endometrial Adenocarcinoma (Neo. Uter.)
- adenocarcinoma or squamous cell carcinomas?
***adenocarcinoma
-Most common malignant tumor of the female genital tract, accounting for approx. 50% of all GYN malignancies
Common in:
- Are taking exognous estrogen in the form of pills or injections
- Have estrogen-producing tumors
- obese & form estrogen at an increased rate by fat tissue conversion.
- DM and HTN
- Are nulliparous or have early menarche and late menopause
-Tumors of the fallopian tubes (Fall. Tubes ?
-
-adenocarcinoma or squamous cell carcinomas?
- **adenocarcinoma
- Rare, & attributable to the fact that epithelium of the fallopian tube does not shed cyclically, like endometrium. Also the muscularis is thin & has cells that don’t respond to estrogenic stimulation as do the myometrial cells.
-Adenocarcinomas are the most common lesion, and these tumors account for 1% of all GYN malignancies
What are the Tumors of surface epithelium (Neo. Ovary)?
-adenocarcinoma or squamous cell carcinomas?
1) Serous,
2) Mucinous
3) Brenner
4) Endometroid
-All tumors of the surface epithelium are either Adenomas or adenocarcinomas.
Which Tumors of surface epithelium (Neo. Ovary) are solid vs cystic?
Serous & Mucinous cystic.
Endometroid & Brenner = more solid.
Describe Serous and mucinous tumors (Tumors of surface epithelium (Neo. Ovary)?
- Classified as what?
- Which the most common form of surface tumors?
- What is Pseudomyxoma Peritonei?
- Classified as benign, borderline (potential), or malignant
- Serous Tumors: (Serous Cystadenoma) Most common form of surface tumors
- Mucinous Tumors : (Mucinous Cystadenoma) Are more often benign (7:1 ratio) and less commonly bilateral (10-30%)
- usually filled with thick, yellowish or clear jelly-like material
- If tumors rupture or the malignant tumors invade the peritoneum, the entire belly is filled w/ mucus. This is called Pseudomyxoma Peritonei.
