Flashcards in Exam 2 Review Deck (74):
1

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.

2

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

3

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

4

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.

5

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)

6

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.

7

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

8

-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)

9

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.

10

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.”

11

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.”

12

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)

13

-What type of cancer is endometrial adenocarcinoma?
-where does it originate from?

-Most common malignant tumor of female genital tract. (50% of GYN malignancies)

-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.

14

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

15

-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.

-

16

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.

17

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.

18

- ____________ pregnancies are ectopic ?

-Rapture occurs ________ after pregnancy.



-1/150
(1/400 die)

-2-6 weeks

19

-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.

20

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.

-Arises from: pre-existing complete hydatidiform mole (50%), placental tissue from abortion (25%), normal placenta after delivery (25%)

-Worst germ cell tumor b/c at time of diagnosis tumor has typically already spread thru bloodstream to lungs & other organs (liver, brain, bones)

-Placenta secrete beta-hCG → used as diagnostic marker and monitoring tumor recurrence after chemotherapy

Notes: -Men can get them too as teratocarcinomas
-Histologically, identical to placenta, endometrial, or testicular lesions

-The most common metastatic tumor being a stomach carcinoma that will tend to produce bilateral enlargement of ovaries.

-(Metastatic Ovarian Tumors) These tumors have estrogen receptors which explains their metastasizing to the ovaries

48

What does a woman usually first have before she has the chance of getting an ectopic pregnancy?

A placental abnormality marked by trophoblastic proliferation & hydropic degeneration of chorionic villi

50

What is the MOST COMMON form of a hydatidiform mole ?


-What is androgenesis?
-What happens without maternal chromosomes?

THE COMPLETE MOLE:
-The fetus cannot be identified in the amniotic sac.
-Results from abnormal fertilization, where all of the chromosomes are PATERNAL in origin due to loss of maternal chromosomes from zygote at the time of fertilization.

Androgenesis = Paternal 23,X set of chromosomes re-duplicates to create 46 chromosomes.

-Without maternal chromosomes, embryo cannot develop, & placenta undergoes hydropic degeneration.

51

Describe an Incomplete hydatidiform mole

-Evolve from oocytes fertilized with 2 spermatozoa, therefore, cells have 69 chromosomes (1 maternal set, 2 paternal sets).

-This combination is LETHAL, but embryo DOESN'T die immediately, so parts of embryo are found encased among the hydropically altered placental villi & normal placental tissue.

52

What is the diagnosis of Hydatidiform Moles based on ?

-H. moles is RARE

-Based on enlarged uterus for
the corresponding, calculated duration of the pregnancy, without any signs of fetal movement.

- Ultrasound is the best method for early detection. Look for Snowstorm Pattern with no fetal heartbeat or movement.

-High serum & urine levels of hCG are typically found. They are aborted spontaneously mid-pregnancy.

-It is important to remove all parts of abnormal placenta. Any remaining trophoblastic cells could give rise to malignant tumors.

53

-Mucous connective tissue in umbilical cord

-Gelatenous substance of umbilical cord that provides insulation & protection

-Also the site of umbilical cord stem cells.

54

What is Meconium?

- Fetal feces & first feces of newborns.
-Sticky, tarry, yucky

55

What is Decidua?

-As the blastocyst implants, into the endometrium it stimulated the Decidual Reaction.

-The cells of the endometrial stroma (fleshy endometrial tissue between glands of inner lining endometrium) accumulate lipids & glycogen, become plump, & are transformed into decidual cells.
-This stroma thickens & becomes highly vascularized, & the endometrium is called DECIDUA & is READY for blastocyst implantation

56

What are Meconium-Stained Placentas?

-Green-colored staining of the fetal membranes that easily rinses off.
-Found in 18% of placentas & occurs most commonly in placentas from pregnancies that are prolonged beyond 42nd wks of gestation.

-Related to acute fetal hypoxia & distress, but this recently has been challenged.

-Major complication of thick meconium is aspiration causing a fetal chemical pneumonitis

-Histologically, there are meconium-laden macrophages w/in fetal membranes.

57

Know the differences between placenta accreta, increta, and percreta based on the levels into the myometrium and beyond

-Placenta Accreta: the attachment of the villi to the level of the myometrium without further invasion
-Can result in uterine rupture, hemorrhage (due to fragments)

-Placenta Increta: villi invade the underlying myometrium

-Placenta Percreta: villi penetrate the full-thickness of the uterine wall

58

Normal parameters of the placenta

-~ 22-24 cm in diameter, and 2.5-3.0 cm thick.
-Weighs approximately 500 gms. (1 lb.)

-The maternal surface is dark red/ maroon in color & divided into lobules or cotyledons. It is important that this structure be complete with no missing cotyledons.

-The fetal surface is shiny, gray & translucent enough to see the color of underlying cotyledons. Fetal membranes (amnio-chorion) are gray, shiny, wrinkled & translucent.

59

Normal parameters of the umbilical cord

-At birth is pearly white, 1-2 cm in diameter, & 50-60cm long.

-It is eccentrically positioned, & contains the right/left umbilical arteries, the left umbilical vein, & mucous connective tissue called Wharton’s Jelly.

-The right/left umbilical arteries carry DEoxygenated blood from fetus to placenta. The umbilical vein carries oxygenated blood from placenta to fetus.

(Presence of 1 umbilical artery within cord is abnormal = cardiovascular abnormality)

60

____________ carries the HIGHEST amount of oxygenated blood from the placenta to the fetus.

The UMBILICAL VEIN

61

Normal parameters of the amniotic fluid ?

-Amniotic fluid volume INCREASES thru the 7th month & DECREASES in the last 2 months.

-At birth volume of amniotic fluid is around 1 liter. Rate of water exchange w/in the amniotic sac is 400-500 ml/hr.

-The term fetus swallows 400ml of amniotic fluid & excretes 500ml of urine daily.

62

What does the Amniotic fluid components contain?

-Electrolytes, carbohydrates, amino acids, lipids, proteins (hormones, enzymes,& alpha-fetoproteins), urea, creatinine, desquamated fetal cells, fetal urine & feces (meconium) & fetal lung liquids (lecithin & sphingomyelin), useful in fetal lung maturity.

-Maternally derived water is similar to blood plasma (continually produced & constantly resorbed)
**L/S ratio - higher (2:1) correlates with lung maturity

63

What are cotyledons and where would you expect to find them?

-15 to 30 divisions of placenta

-found on the maternal side of placenta

-consists of main stem of chorionic villus

-cotyledons remaining in mother AFTER birth causes post-partum hemorrhaging

64

Which hormone secreted from the placenta is known as the growth hormone for the fetus?

-Human Placental Lactogen (hPL):
protein hormone that induces lipolysis thus elevating free fatty acid content in mom

65

What is the differenece between succenturiate placenta vs circumvallate placenta?

(Accessory) Succenturiate = EXTRA lobes
-linked by thin chorionic tissue
- No clinical importance, unless a portion of lobe is retained after birth - post-partum bleeding

Circumvallate = rolled & raised ring of fetal membrane
over fetal surface instead of edge of placenta (chorionic plate < basal plate).
-The blood vessels at chorionic plate stop at raised membranes & run deeper under membranes.
-Associated w/ Prematurity
Prenatal bleeding, Placental abruption or Multiplarity (more than on fetus)

66

What is the Normal distribution of umbilical cord, how many arteries and veins?

-Wharton’s Jelly - mucous connective tissue

*3 vessels:
Left and right umbilical arteries:
Carry DE-oxygenated blood FROM fetus to placenta

Umbilical vein:
Carry oxygenated blood from placenta TO fetus

67

What is the condition of amnion nodosa?

-Numerous small, gray /yellow nodules on fetal surface of placenta, associated with:
***Oligohydramnios(low amount of amniotic fluid)

***Renal Agenesis (POTTERS SYNDROME) as a result of oligohydramnios (decrease amt of amniotic fluid, can leads to-->no endometrium cushion-->pulmonary disorder)

68

What is the most common complication of a baby being born with amniotic fluid thick with meconium?

Aspiration causing fetal chemical pneumonitis

69

What is acute chorioamnionitis and what organisms can cause this condition? What is the most common cause of chorioamnionitis?

-anaerobic Bacteroides group

-Aerobe Group B Streptococcus, E. coli & Gardnerella vaginalis

- Caused by premature rupture of amniochorionic membranes (PROM)

-Amniontic fluid = cloudy and walls opaque, malodorous & edematous.

70
