Q

Salpingitis Isthmica Nodosa

  • complications
  • location
A
  • infertility, ectopic pregnancy - cause the lumen of the FT gets constricted and small
  • Bilateral in 80% of cases with nodular swellings
    swelling caused by diverticulae communicating with lumen cause swellings

Q

mature teratomas

A

mature teratomas form majority of germ cell tumours

benign: cystic teratoma (colour resembles thyroid follicles w/ colloid),
Struma ovarii
malignant: SCC, thyroid

(immature teratomas are all malignant)

Q

yolk sac tumour

  • affects who
  • malignancy
  • characteristics
A
  • Children and young women
  • Highly malignant
  • Differentiation towards yolk sac
    Rich in alpha-fetoprotein -> tests strongly for AFB
    Schiller-Duval bodies - central fibrovascular space
17
Q

surface epithelium tumours

A
- Endocervical differentiation: 
Mucinous tumours - cystadenoma (B) and cystadenocarcinoma (M)
- Tubal differentiation: 
Serous tumours - cystadenoma (B) and cystadenocarcinoma (M)
- Endometrial differentiation: 
endometrioid and clear cell (M) type 
- Transitional/urothelial: 
Brenner tumour (B)
B = beign
M = malignant
18
Q

pathogenesis of ovarian epithelial tumours (2 types)**

A

Type 1 tumours: progress from benign through borderline tumours that give rise to low-grade carcinomas.
Type II tumours: arise from inclusion cysts/FT epithelium that show high grade features (serous)
- majority of malignant epithelial tumours are serous!!**

19
Q

mucinous cystadenoma histo features

A

lined by mucin epithelium

locule containing mucin

20
Q

borderline ovarian neoplasms histo criteria

A
  • Epithelial hyperplasia – stratification, tufts
  • Atypia –mild to moderate
  • Minimal mitotic activity
  • Absence of destructive stromal invasion
21
Q

mucinous tumours

  • clinical presentation
  • complications
A
  • massively enlarged abdomen

- rupture -> release mucin into peritoneal cavity

22
Q

endometroid ovarian tumour

  • malignancy
  • histo features
  • prognosis
A

most of them are malignant

  • Contain tubular glands resembling endometrium
  • prognosis better than serous carcinoma
23
Q

clear cell ovarian adenocarcinoma

- gross and histo appearance

A

uncommon
- Grossly solid/cystic
- Large sheets of epithelial cells with clear cytoplasm and tubules with hobnail nuclei (bulbous nuclei w/ projections into cytoplasm)
cystic spaces lined by nucleus

24
Q

brenner tumour

  • malignancy
  • size
  • histo appearance
A
  • Benign
  • 1-8cm
  • Nests of urothelial-like cells in a dense fibrous stroma
25
Q

sex cord/stromal tumours

  • malignancy
  • types
A

mainly benign - low grade malignancy

  • thecomas (fibroma)
  • granulosa cell (most common)
26
Q

thecoma (fibroma)

  • malignancy
  • histo features
  • clinical presentation
A
  • benign
  • Stromal tumours with fibroblasts (fibroma) or plump spindle cells with lipid droplets (thecoma)
  • Meig’s syndrome: Fibroma, ascites, pleural effusion
27
Q

granulosa cell tumour

  • malignancy
  • gross and histo appearance
A
  • malignant: spreads locally
  • large tumour (cystic/solid). yellow areas (lipid laden luteinized cells)
  • Follicular pattern (call-exner bodies)
    Cleaved, elongated nuclei (coffee bean shape)
28
Q

spread of malignant ovarian neoplasms (4 ways)

A
- Local infiltration into broad ligament:
Urethral obstruction
Bladder involvement
- Peritoneal spread
Ascites with malignant cells in fluid
Peritoneal nodules
- Lymphatic spread
- Hematogenous spread
