Q

This is the metaplastic lesion where the epithelium transforms into cystic spaces filled with clar fluid lined by flattened urothelium.

A

Cystitis cystica

27
Q

True or False: metaplastic lesions showing extensive intestinal metaplasia have an increased risk of developing adenocarinoma.

A

FALSE. They do not.

except when assocaited with exstrophy… lol

28
Q

What causes squamous metaplasia in the bladder?

29
Q

Squamous metaplasia should be distinguised from what form of epithelium normally found at the trigone in women?

A

Glycogenated squamous epithelium

30
Q

These is the tumor shed from renal tubular cells that inplant in sites of injured urothelium.

A

Nephrogenic adenoma

31
Q

The overlying urothelium of neprhogenic adenomas may be focally replaced by what epithelium, which can assume a papillary growth pattern?

A

Cuboidal epithelium

32
Q

What are the 2 forms of urothelial/transitional tumors?

A
  1. Non-invasive papillary tumors (most common)

2. Flat non-invasive urothelial carcinoma (carcinoma in situ)

33
Q

In flat urothelial carcinomas, what is the gross morphology of the area?

A

Area of mucosal reddening, granularity, or thickening without producing an evident mass.

34
Q

This is the name of the spread of flat urothelial carcinomas where there is scattered malignant cells in an otherwise normal urothelium.

A

Pagetoid spread

35
Q

This is the type of urothelial cancer wehre there is invasion into muscularis mucosae and spreads.

A

Invasive urothelial cancer

36
Q

What are the 4 high yield risk factors for urothelial carcinoma?

A
  1. SMOKING
  2. Napthylamine
  3. Azo-dyes (hairdressers)
  4. Long term cyclophosphamide or phenacetin use
37
Q

What is the presentation of urothelial carcinomas?

A

Painless hematuria

38
Q

In papillary growths of urothelial carcinomas, what is the progression of the disease?

A

Low grade –> high grade –> invade

39
Q

For flat urotheial carcinomas, what is the progression of the disease?

A

Start HIGH grade –> invade

40
Q

What mutations are assocaited with flat urothelial carcinomas?

A

early p53 mutations

41
Q

What must be ruptured in both papillary and flat urothelial carcinomas to become invasive?

A

The basement membrane

42
Q

Since the bladder doesnt normally have quamous cells, what must occur to have squamous cell carcinoma?

A

Metaplasia to squamous cells –> dysplasia –> cancer

43
Q

What is the high yield infection that predisposes you to squamous cell carcinomas?

A

Shistosoma hematobium

44
Q

What type of person may classically present with squamous cell carcinomas from schistosoma hematobium infections?

A

Middle eastern male

45
Q

What 2 chronic conditions are risk factors for squamous cell carcinomas?

A

Chronic cystitis

Long-standing nephrolithiasis

46
Q

True or False: it is more common in squamous cell carcinoma for have mixed urothelial carcinomas with areas of squamous carcinoma than just pure squamous cell carcinoma.

47
Q

This is the type of cancer from the malignant proliferation of the glands of the bladder.

A

Adenocarcinoma

48
Q

What are the 3 high yield associations for adenocarcinomas?

A
  1. Urachal remnant
  2. Cystitis glandularis
  3. Exsotrophy
49
Q

Where is the common location in the bladder for adenocarcinomas from urachal remnants?

A

Dome of the bladder

50
Q

Urothelial, suqamous, or adenocarcinomas are assocaited with the formation of what other cancer type in the bladder?

A

Small cell carcinoma

51
Q

What is the most import risk factor for bladder cancer?

52
Q

30-60% of bladder cancer have what 2 genetic alterations?

A

Chromosome 9 monosomy

Deletions of 9p and 9q (as well as deletions of 17p, 13q, 11p and 14q).

53
Q

Deletion of 9p stops the production of which tumor suppresor gene?

A

p16 (INK4a)

54
Q

Deletion of 17p stops the production of which tumor suppresor gene?

55
Q

After tumor removal, what is common in bladder cancers?

A

Recurrence

56
Q

What is the diagnostic tool for bladder cancers?

A

Cystoscopy + biopsy

57
Q

What is the treatment for small, localized, non high grade bladder cancer?

A

transurethral resection

58
Q

What is the Tx for tumors invading muscularis propria, CIS, or high grade papillary cancer?

A

Radical cystectomy

59
Q

In males, what typically obstructs the bladder neck?

60
Q

In females, what typically obstructs the bladder neck?

61
Q

What happens in the early stages of bladder neck obstruction?

A

SM hypertrophy and trabeculations in the bladder

62
Q

What happens in the later stages of bladder neck obstruction?

A

Diverticula

63
Q

What causes markely thinned bladder without trabeculations of the bladder?

A

Acute obstruction or terminal disease
