Q

Name a rare testicular non-germ cell tumour that may present with precocious puberty in pre-pubertal boys ?

A

Leydig cell tumour

17
Q

List 3 testicular non-germ cell tumours ?

A

Lymphoma
Leydig cell tumour
Sertoli tumour

18
Q

Which type of urinary calculi are most common ?

A

Calcium oxalate

19
Q

List 2 causes of urate stones ?

A
  • Gout

- Chemotherapy

20
Q

What is the most common type of prostate cancer ?

A

adenocarcinoma

21
Q

Which 3 markers are raised in teratoma ?

A

AFP
HCG
LDH

22
Q

causes of the 3 types of stone

A

calcium oxalate (95%) - hypercalciuria

  • absorptive hypercalciuria - too much absorbed in gut
  • renal - impaired absorption in proximal renal tubule

magnesium ammonium phosphate (15%) - infection with urease-producing organisms (proteus)
- can be large (staghorn calculus)

uric acid (5%)- hyperuricemia 
- gout/rapid cell turnover (eg chemo)
23
Q

where do stones tend to lodge

A

pelvi-ureteric junction
pelvic brim
vesico-ureteric junction

large stones stay in the kidney and lead to:

  • obstruction
  • risk of infection
  • CKD
24
Q

list benign renal neoplasms

A

papillary adenoma
renal oncocytoma
angiomyolipoma

25
Q

features of papillary adenoma

A
benign epithelial kidney tumour 
made of papillae/tubules 
= 15mm 
well-circumscribed
trisomy 7, 17, loss of chromosome Y
26
Q

features of renal oncocytoma

A

benign epithelial kidney tumour made of oncocytic cells
well circumscribed
sporadic
seen in birt-hogg-dube syndrome
usually incidental finding
oncocytes = large cells with pink granular cytoplasm and prominent nucleolus

27
Q

features of angiomyolipoma

A

benign mesencyhmal kidney tumour made of thick-walled bv, smooth muscle and fat
see in tuberous sclerosis
large tumours (>4cm) present with flank pain, haemorrhage and shock

28
Q

features of renal cell carcinomas

A

malignant epithelial kidney tumours
mainly presents with PAINLESS HAEMATURIA
subtypes = clear cell renal cell carcinoma, papillary renal cell carcinoma, chromophobe renal cell carcinoma

29
Q

papillary renal cell carcinoma

A

> 15mm
trisomy 7, 17, loss of Y chromosome
type 1 - single layer of small flat cells
type 2 - stratification of the cells

30
Q

chromophobe renal cell carcinoma

A

sheets of large cells with distinct borders, reticular cytoplasm and a thick-walled vascular network
variable genetic abberations
well-circumscribed and solid brown

31
Q

nephroblastoma (wilm’s tumour)

A

malignant triphasic kidney tumour of childhood
presents as an abdominal mass aged 2-5 yrs
excellent prognosis

32
Q

features of urothelial carcinoma

A

aka transitional cell carcinoma
RF = smoking + aromatic amines
subtypes = non-invasive papillary urothelial carcinoma, infiltrating urothelial carcinoma, flat urothelial carcinoma in situ

33
Q

features of BPH

A

benign enlargement of the prostate as a consequence of increased cell numbers
? increased oestrogen in the blood due to ageing - indices androgen receptors
presents with LUTS - FUND HIPS

34
Q

features of prostatic adenocarcinoma

A

malignant epithelial prostate tumour
most common malignant tumour in men
arises from prostatic intraepithelilal neoplasia
mutations include - PTEN, AMACR, GST-pi, p27
gleason score
