Q

What does the eastrogen produced by the granulosa do

A

It hits the oocyte and causes it to mature as well as it causes the endometrium to enter the proliferative phase

Q

What happens in Polycystic ovarian disease (PCOD)

A

Due to high levels of LH -
The theca cells will secrete a shit ton of androgens and when it goes into blood -> it causes hirstrism(hair growth on face and arms etc) - the androgens will also go in to periphery in to adipose tissue and it will get converted in to estrons.

14
Q

What does estron do in the body

A

It will go feed in to the anterior pituitary and decrease production of FSH, hence granulosa cells won’t be able to convert the androgen-> leading to degeneration of follicle ( decrease in estrogen to maintain the follicle) and that all results in cyctic formation

21
Q
  • benign tumour of epithelium of the ovary
  • can be mucinous or serous
  • composed of single cyst with simple flat lining
  • most commonly arises in premenopausal women(30-40 years old)
22
Q

Malignant tumour of the epithelium layer of the ovary can by mucinous or serous

  • composed of complex cyst with thick shaggy lining
  • most commonly arises in post menopausal women 60-70 years old
Study These Flashcards
A

Cyst adenocarcinoma

23
Q
  • tumour features in between benign and malignant tumours

- better prognosis than clearly malignant tumours but still carry metastatic potential

Study These Flashcards
A

Borderline tumours

24
Q

BRCA 1 Mutation carriers

Study These Flashcards
A

Have increased risk for SEROUS carcinoma of the ovary and Fallopian tube

25
What are other types of surface epithelial tumours
Endometroid and Brenner tumour
26
- usually a malignant tumour of the surface epithelium | - associated with endometriosis of the ovary (chocolate cyst)
Endometrioid tumour of the ovary | -15% of people with endometrial carcinoma of the ovary will have separate endometriod carcinoma of the endometrium
27
Tumour of the surface of the ovary that contains urothelium in the ovary
Brenner tumour
28
Surface tumours present late —>
- Vague abdominal symptoms (pain, fullness) - signs of compression - poor prognosis - epithelial carcinomas tend to spread locally especially to the peritoneum (shows omental caking)
29
Which tumour marker does surface epithelial tumours release
CA-125 —> useful serum marker to monitor treatment response and screen recurrence
30
What is the second most common ovarian tumour
Germ cell tumours (15%)
31
- usually occur in women of reproductive age (15-30 yes) | - tumour subtypes mimics tissues normally produced by germ cells.
Germ cell tumours
32
Types of tumours of feral tissue
Cystic teratoma or emberyonal carcinoma
33
Type of tumors in the yolk sac
Yolk sac tumour
34
Type of tumours of germ cells
Dysgenioma
35
Type of tumours of placenta
Choriocarcinoma
36
What is the most common germ cell tumour in females
Cystic teratoma
37
- A tumour composed of fetal tissue derived from 2-3 embryologic layers, bilateral 10% of the cases. - Tumour is composed of (Bone, hair, teeth, gut …..) - benign (MATURE TERATOMA) but if there is immature tissue (neural ectoderm) it indicates malignancy or also somatic malignancy —> making it IMMATURE TERATOMA
Cystic teratoma
38
- Cystic teratoma composed primarily of thyroid tissue | - can also present with hyperthyroidism and mass in the ovary or
Monodermal teratoma (struma ovarian)
39
- a mass of a bunch egg like cells - composed of large cells with clear cytoplasm and central nuclei - most common malignant germ cell tumour - testicular counterpart is called seminoma - good prognosis responds to radiotherapy - serum LDH is elevated
Dysgerminoma
40
- malignant tumour that mimics yolk sac - most common germ cell tumour in children (a girl who’s 5years old) - serum AFP is elevated - schiller-duval bodies (glomeriliod-like structures)are seen on histology
Endoderm all sinus tumour
41
-tumour composed of trophoblasts and syncytiotrophoblasts (villi are absent) - high B-HCG (Human chorionic gonadotropin ) - small hemorrhagic tumour with early hematogenous spread (poor prognosis) (Happens because trophoblasts are programmed from the beginning to invade)
Choriocarcinoma
42
- resembles granulosa cells theca cells, fibrous tissue and rarely sertoli/leydig cells
Sex cord stromal tumours
43
- neoplasm of granulosa and theca cells - often produces estrogen - presents with signs of estrogen excess (symptoms vary with age)
Granulosa theca cell tumour
44
- Sertoli cells from tubules - leydig cells contain a characteristic REINKE CRYSTALS. - may produce androgens, associated with hirsutism or virilization
Sertoli leydig tumour
45
Benign tumour of fibroblasts | Associated with pleural effusions and ascites (meigs syndrome)
Fibroma
46
Diffuse gastric carcinoma with finger shaped cells involved both ovaries primary involves only one
Kuckenberg tumour
47
Metastasis means the cancer will be
Mucinous carcinoma
48
A lot of mucus in peritoneum usually due to mucinous carcinoma of the appendix
Pseudomyxoma peritonei
49
The implantation of a fertilised ovum in any other site than the uterus (90% of these cases is in the oviductal tubal pregnancy)
Ectopic pregnancy
50
- inflammation of the Fallopian tube with pus occurs as a part of PID. - scarring of the tube and increased risk of ectopic pregnancy
Supportive salpingitis
51
- most common benign Fallopian tube tumour | - mesothelial in origin
Adenomatoid tumour
52
- benign cysts arising from mullerian vestiges, below the Fallopian tube near fimbriae - no significance until it’s torted -> leleading to infarction
Hydatids of morgani
