Q

Outline the management of a follicular cyst.

A

Usually resolve over a few months !! …

  • Get patient to come back in a few months, if smaller then good
  • If bigger, then think neoplastic cyst

25
What are the 6 different subtypes of epithelial ovarian tumour?
* Serous * * Mucinous* * Endometrioid* * Clear cell * * Brenner* * Undifferentiated carcinoma All above with ‘*’ can be differentiated into; benign, borderline or malignant
26
What % of all ovarian tumours do epithelial account for?
65-70%
27
Describe benign epithelial ovarian tumours.
* No cytological abnormalities, proliferative activity absent or scant * No stromal invasion
28
Describe borderline epithelial ovarian tumours.
* Cytological abnormalities, proliferative
29
Describe malignant epithelial ovarian tumours.
* Stromal invasion
30
What is a high grade serous carcinoma also known as?
Serous tubal intraepithelial carcinoma (STIC)
31
What is a low grade serous carcinoma also known as?
Serous borderline tumour
32
What is the treatment for serious carcinoma of the ovary?
SURGERY !! - think s for s
33
What do low grade serous tumours not respond to?
Chemotherapy
34
What are the 2 histological features of a high grade serous carcinoma?
* Prominent nucleoli | * Pleomorphic
35
What ovarian cancers have a strong association with endometriosis of the ovary?
Endometrioid and Clear Cell Carcinoma
36
What are Endometrioid and Clear Cell Carcinoma associated with (syndrome?)
Lynch Syndrome
37
How is the diagnosis of Endometrioid and Clear Cell Carcinoma made?
On ascitic fluid
38
What is Brennen a tumour of?
Transitional type epithelium
39
What % of all ovarian tumours are germ cell tumours?
15-20%
40
What are germ cell tumours also known as?
TERATOMAS !!
41
What accounts for 95% of all germ cell tumours?
Mature (benign, cystic) Teratoma
42
What accounts for 95% of all germ cell tumours?
Mature (benign, cystic) Teratoma
43
What is odd about teratomas?
These are CYSTIC and can contain sebum and hair
44
What are teratomas derived from?
Derived from all 3 embryonic layers – ectoderm, mesoderm, endoderm
45
What are 4 common components of teratomas?
* Skin * Respiratory epithelium * Gut * Fat
46
List other germ cell tumours that are not mature teratomas.
* Immature teratoma * Dysgerminoma * Yolk sac tumour * Choriocarcinoma * Mixed germ cell tumour
47
A Dysgerminoma is the most common malignant/benign primitive germ cell tumour?
Malignant
48
Who do Dysgerminoma's occur exclusively in? What is the average age of this?
Occur exclusively in children and young women Average age - 22
49
A Fibroma/Thecoma is benign
TRUE
50
What may Fibroma/Thecoma's produce? What does this cause?
Oestrogen - uterine bleeding
51
All granulose cell tumours are potentially __________
Malignant
52
Sertoli-Leydig Cell Tumours are ____ and may produce _________
1. Rare | 2. Androgens
53
What colour is an ovarian fibroma? Why?
Yellow – granulosa, hormone producing cells
54
What primary cancer sites are the commonest for producing ovarian mets?
* Stomach * Colon * Breast * Pancreas
55
When should you consider metastatic ovarian tumours?
This must be considered in ALL cases, especially if the tumour is bilateral and small !!
56
Bilateral and small ovarian tumours means what?
Probably metastatic disease
57
List 5 different fallopian tube pathologies.
* Inflammation - Salpingitis due to infection * Cysts and tumours * Serous tubal intraepithelial carcinoma * Endometriosis * Ectopic pregnancy
58
What staging system is used for ovarian cancer?
Figo
59
'Finger like processes of the uterine tubes can become inflamed'. What condition is this seen in?
PID
60
What cell type is seen in tissues with PID which should b there?
Inflammatory cells
61
Why may tubes in PID not function properly?
Tubes may not function properly as adhesions form between the processes due to the inflammation
62
What is an ectopic pregnancy?
Implantation of a conceptus outside the endometrial cavity
63
Where is the commonest site for an ectopic pregnancy?
Fallopian tube
64
Where else (except fallopian tubes) can an ectopic pregnancy occur?
* Ovary | * Peritoneum
65
Why can an ectopic pregnancy sometimes be fatal?
Often ruptures, potentially causing fatal haemorrhage
66
* Amenorrhoea * Acute hypotension * Acute abdomen If a female has any of the above, what should you always consider?
Ectopic pregnancy
