Q

what are cystitis cystica and cystitis glandularis?

A

chronic inflammatory conditions that occur in the setting of chronic irritation

irritants are usually infection, calculi, outlet obstruction or tumor

26
Q

how are CC and CG related?

A

urothelium proliferates into buds which grow into CT beneath the epithelium into the lamina propria

the buds then differentiate into cystic depositions of CC or into intestinal columnar mucin-secreting glands resulting in CG

both forms are usually found on histo

27
Q

what is follicular cystitis?

A

aggregation of lymphoid follicles in the mucosa and underlying wall

typically associated with chronic infection

28
Q

what is eosinophilic cystitis?

A

infiltration of submucosal eosinophils from nonspecific subacute inflammation or systemic allergic reaction, autoimmune disorder, parasitic infection

29
Q

what is rhabdomyosarcoma?

A

malignant mesenchymal tumor typically seen in children

30
Q

what is leiomyosarcoma?

A

malignant mesenchymal tumor typically seen in adults

possibly caused by radiation or chemo

31
Q

what is primary malignant lymphoma?

A

hematologic malignancy seen in adults with chronic cystitis

usually non-hodgkin lymphoma

32
Q

what environmental risk factors are associated with urothelial carcinoma?

A 
smoking
industrial exposure to arylamines
schistosoma hematobium 
analgesics
cyclophosphamide
radiation
33
Q

what genetics risk factors are associated with urothelial carcinoma?

A

Chrom 9 monosomy or deletions

Chrom 17p deletions (p53)

34
Q

what mutations are almost always seen in urothelial carcinoma?

what is autoimmune orchitis?

A

idiopathic orchitis that presents in middle age as a tender testicular mass with fever

Q

what is testicular torsion?

A

twisting of the spermatic cord that cuts of venous drainage of the testis

if untreated leads to testicular infarction

what is the most common benign paratesticular tumor?

A

adenomatoid tumor
