Q
What test do you do after seeing an abnormality from a pap smear? and then what?
A
If you see an abnormality on the pap smear, do a colposcopy (visualization of mucosa), and if still abnormal do a biopsy
19
Q
procedures for high grade SIL (squamous intraepith neo aka CIN or cervical neo) vs low grade?

how often should females have pap?
every 3 yr starting at age 21 etc
30
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
Mastitis
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
Fat necrosis
| cause and histo
trauma or prior surg which can mimic carc
-fibrosis and EGG SHELL CALCIFICATIONS with FOAMY MACROPHAGES and LIPID-FILLED CYSTS, can be from seatbelt, sports, etc (tender and lumpy)
33
Fibrocystic breast changes - 2 forms
```
Nonprolif
and prolif (+/- cellular atypia)
```
34
nonprolif fibrocystic breast change
stromal fibrosis, cyst, apocrine metaplasia, and adenosis (of myometrium?) (DONT incr risk for BC dev)
35
prolif fibrocystic breast change
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
36
Fibrocystic BREAST changes are found in which pathologies?
1 Atypical ductal hyperplasia
2 Fibroadenoma
3 Phyllodes tumor
4 Intracellular papilloma
37
Atypical ductal hyperplasia
lesion w SOME features of low grade ductal carc in situ (not DCIS)
-when hyperplasia incl 2 types of cells (normal), if only one cell found its more worrisome
38
```
Fibroadenoma
gross appearance
features
pop
sx
```
Benign tumor with CT and epith prolif, most common breast tumor in young ppl, more in AA pts
- well circumscribed FREELY MOVABLE nonpainful mass
- CAN ENLARGE WITH PREG AND REGRESS as it responds to estrogen
- tubular and lactating adenomas most common
39
Phyllodes tumor
gross/histo
-etc
Fleshy tumor with leaflike pattern
- made of CT and epith, more CT than fibroadenomas tho, uncommon
- can be benign borderline OR malig--> if malig spreads thru blood
40

42
risk of developing or dying from BC
| survival rate
- 1/8 risk , 1/35
- second leading cause of cancer death among women
- 5 year survival rate is 90%
43
Breast Cancer risk factors
older, f hx, mutations like brca, AA, estrogen exposure like early menarche, late menopause, nullparity etc, obesity and western diet, radiation etc
44
BRCA-1 vs BRCA-2 mutations
- BRCA-1 BC risk increases in elderly, ovarian prostate pancreas and fall tube neoplasms also
- BRCA-2 is ovarian and male BC in addition
45
signs of BC
breast mass, asymmetric thickening, bloody nipple discharge/scaling(pagets/ dimpling, erythema/ pain etc
46
subtyes of bc
in situ and INVASIVE
- most is invasive- mostly DUCTAL
- rest is in situ carc- mostly ductal (rest is lobular)

- pale staining malig cells within the epidermis
55
LCIS (Lobular carcinoma in situ)
carc of intralobular ductules which are damaged by loosely aggregated cells without stromal invasion, usually bilateral
56
Invasive lobular carcinoma
- levels
- mets
- histo
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
which cancers have favorable, unfavorable, and poor px based on levels
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
which cancers are BRCA2/DCIS
which cancers are HER2+
Which cancers are tBRCA1 basal like
- luminal!
- germline p53 and atypical apocrione adenosis
- triple neg
59
Gynecomastia
- apperance
- assoc
- type of carc
Subareolar mass, soemtimes bilateral
- assoc with cirrhosis, RF, pulm dis, hormones /drugs
