Central
Peripheral
Transitional
Periurethral
4
Most carcinomas arise from which zone of the prostate gland?
Peripheral glands
5
Nodular hyperplasia typically occurs in which zone of the prostate gland
Central zone- causes urinary obstruction before carcinomas
6
Describe the growth of prostatic nodules in older men, compared with younger me
In older men they form and enlarge
In younger men (
7
Main cause of nodular hyperplasia
Impaired cell death- acumulation of senescent cells in the prostate
8
What role do androgens play in nodular hyperplasia?
They are able to increase cellular proliferation and inhibit cell death
9
What is the most common prostatic carcinoma?
Prostatic adenocarcinomas (95% prostatic malignancies)
10
In which age groups/ethnicities are prostatic adenocarcinomas most common?
>40yrs, increase incidence in african ancestry
11
Risk factors for prostatic carcinomas
Age
Race

FH
BRCA2 mutation
12
How significant are BRCA2 mutations in increasing the risk of prostatic carcinoma?
x20 increased risk
13
What is the scoring system for prostatic carcinomas
Gleason's scoring system

PLAP and hCG
23
What is the cause of gynacomastia in seminomas
hCG
24
What hormones are secreted by teratomas?
Pure teratomatous tissues do not secrete tumour markers

Teratoma
27
Which type of germ cell testicular tumour is made up of monotonous polygonal cells with mostly clear cytoplasm and central nuclei divided into lobules by thin bands of fibrovascular stroma
Seminoma
28
Which type of germ cell testicular tumour is an admixture of ectoderm and mesoderm
Teratoma
