Q

Testicular tumors

  • pop
  • 3 types
  • 6 assocations with testicular cancer
  • dx/biomarkers
A
  • pop: most common malig in young men, second peak in elderly, more common in right testis, caucasians
  • 3 types: germ cell tumors (seminoma/ embryonal/ yolk sac/ choriocarc/ teratoma/ mixed), stromal tumor (leydig, sertoli), and lymphoma
  • 6 assoc: crypotorchidism, prior history, prior fam history, intersex, infertility, intratubular germ cell neopl
  • dx: dont biopsy bc can contaminate, markers like AFP and B-HCG

every 3 yr starting at age 21 etc

30
Q

fxnl unit of breast?

what are the 2 cells involved?

the TDLU (terminal duct lobular unit), small duct coming from lobule surr by fibrous stroma
-2 cell types: luminal epith cells and myoepith cells
31
Q

Mastitis

A

inflammat changes in breasts, shouldnt be biopsied due to bact or virus (eg staph), would give neutros (chronic woudl show up as lymphos/plasma cells)

silicone granulomas can also happen, would show foamy histiocytes with silicone granules

32
Q

Fat necrosis

trauma or prior surg which can mimic carc

Nonprolif
and prolif (+/- cellular atypia)

Q

nonprolif fibrocystic breast change

stromal fibrosis, cyst, apocrine metaplasia, and adenosis (of myometrium?) (DONT incr risk for BC dev)

35
Q

prolif fibrocystic breast change

A

epith hyperplasia, sclerosing adenosis, small duct papilloma, and clerosing lesions– all incr risk for BC and cellular atypia increases it even more, carc in situ has highest risk of dev into invasive carc

2 Fibroadenoma
3 Phyllodes tumor
4 Intracellular papilloma

features
pop
sx

51
Q

Mucinous carcinoma

-histo, genetics, px

A

tumor w malig clusters of cells floating in POOLS OF EC MUCIN (v distinguishable appearance)

  • most ER/PR+ with FAVORABLE px
52
Q

Medullary carcinoma

-genetics, px/mets, histo, pop, gross

  • younger pts with BRCA-1 mutation
53
Q

Papillary carcinoma

-histo, sx, px, pop

A
  • cancer with fingerlike projections, postmenopause, many have papillary DCIS and can have BLOODY NIPPLE DISCHARGE

54
Q

Paget’s disease of the nipple

-sx, histo

A
  • pain/itching/scaling/redness of nipple which may have ulceration, crusting, and serious/bloody discharge
  • mistaken for ECZEMA
  • pale staining malig cells within the epidermis
55
Q

LCIS (Lobular carcinoma in situ)

carc of intralobular ductules which are damaged by loosely aggregated cells without stromal invasion, usually bilateral

56
Q

Invasive lobular carcinoma

  • levels
  • mets
  • histo
A

Invasive carcinoma of uniform cells resembling LCIS, low mitotic rate

  • can be bilateral, can mets to csf, body cavities and ovaries
  • E-cadherin negative
  • cells line up in single file line
57
Q

which cancers have favorable, unfavorable, and poor px based on levels

A

ER/PR+, HER2- favorable
ER/PR-, HER2+ unfavorable and harder to tx
Triple negative ER/PR/HER2- has v poor px (Basal-like cancers)

58
Q

which cancers are BRCA2/DCIS
which cancers are HER2+
Which cancers are tBRCA1 basal like

A
  • luminal!
  • germline p53 and atypical apocrione adenosis
  • triple neg
59
Q

Gynecomastia

  • apperance
  • assoc
  • type of carc
A

Subareolar mass, soemtimes bilateral

  • assoc with cirrhosis, RF, pulm dis, hormones /drugs
