8.12 Lower Urinary Tract Flashcards
(27 cards)
most common malignant tumor of ureter
transitional cell carcinoma
present w/ obstruction in 60s-70s
transitional cell carcinoma
bladder exposed through anterior abdominal wall called
- increased risk for
exstrophy
adenocarcinoma of colon or bladder
what drugs and treatments can cause cystitis (UTIs)
chemo drugs (cyclophosphamide) and radiation
histo appearance of chronic cystitis
lymphocytes and plasma cells
chronic cystitis without evidence of bacterial infection, but might have chronic mucosal ulcers (Hunner ulcers) and mast cells in bladder wall
interstitial cystitis
soft, yellow mucosal plaques with foamy macrophages and also lymphocytes
- also see what
malacoplakia
Michaelis Gutmann bodies (laminated mineralized concretions resulting from calcification of enlarged lysosomes)
exaggerated Brunn nests
cystitis glandularis / cystica
results from shed renal tubular cells that implant in injured urothelium
nephrogenic metaplasia “adenoma”
Urothelial / transitional cell tumors are in
bladder
bad prognosis for urothelial cell tumors
invasion of muscularis propria
retain blood group antigens (A,B,H)
low grade papillary urothelial carcinoma
papillary tumors w/ loss of polarity, cytologic atypic, frequent mitoses
high grade papillary urothelial carcinoma
lacks blood group antigens (A,B,H)
high grade papillary urothelial carcinoma
malignant cells within a flat urothelium (basement membrane is intact w/ no invasion)
carcinoma in situ
tumor cells in urine
high grade papillary urothelial neoplasm
carcinoma in situ
schistosomiasis increases risk of what cancer
squamous cell carcinoma
looks like rectal, uterine, colon cancer
adenocarcinoma of the bladder
signet ring cell tumor is a variant of
adenocarcinoma of the bladder
tumor genetics
chromosome 9 monosomy or deletions of 9p and 9q
deletions or mutations of 13q, 14q, 17p
painless hematuria in older patients
- 3 treatment options
urothelial carcinoma
localized low grade: transurethral resection
multifocal low grade: topical chemo
high risk: BCG
radical cystectomy is indicated when
tumor invades muscularis propria
CIS or high grade papillary neoplasms refractory to BCG
CIS extending into prostatic urethra and into prostatic ducts (beyond reach of BCG)
arthritis, conjunctivitis, urethritis
Reiter syndrome
2 urethral carcinomas and locations
proximal urethra: urothelial carcinoma
distal urethra: squamous cell carcinoma
