Breast Diseases Flashcards
what is the most common cause of benign breast disorders?
fibrocystic breast changes
what are fibrocystic breast disease influenced by?
hormones
fibrocystic breast disease sx’s worse when?
sx’s worse prior and during menstrual cycle b/c relates to the hormones
pathogenesis of fibrocystic breast disease?
hormone induced breast changes
what is created in fibrocystic breast disease?
estrogen-ductal elements -> cause discomfort and hyperplasia
is fibrocystic breast changes a disease?
no, it’s a normal variation in breast histology
risks for fibrocystic breast disease?
nulliparity, late menopause, estrogen replacement therapy
what is the clinical presentation of fibrocystic breast disease?
tender bilateral breast w/palpable nodule that blends into the surrounding breast tissue
lumpiness fluctuates with the menstrual cycle (increase and decrease in size)
what is the nodule like in fibrocystic breast disease?
smooth well-defined edges
freely moving (not hard)
is there usually a mass present in fibrocystic breast disease? if there is?
no there usually isn’t, but if there is then do US +/- FNA
when do you follow up for fibrocystic breast disease if equivocal or non-suspicious on exam?
re-examine in 2-4 weeks (follicular phase of menstrual cycle, days 5-7 best)
what is the best dx imaging for fibrocystic breast disease? what does it distinguish?
US
Distinguishes cystic from solid mass
US for fibrocystic breast disease is done before what? can use US to do what for FNA?
before a FNA - can use US to do needle guided FNA
what does it mean when fluid from cyst comes back clear? if mass is solid?
if clear = cyst
if solid = mammogram
when is mammogram used for fibrocystic breast disease?
Further evaluation of clinically suspicious masses
Further evaluation of solid masses
dx procedures for fibrocystic breast disease?
FNA or Core Needle Bx
when is FNA best done for fibrocystic breast disease?
after US to distinguish b/w a solid and cystic mass
if no aspiration or bloody aspiration from FNA of fibrocystic breast disease, what is the next step?
Core Needle Bx
can FNA be therapeutic for fibrocystic breast disease?
YES! can take off some fluid to decrease pain
what is the difference b/w FNA and Core Needle Bx?
FNA = cytology
Core Needle Bx = histology
Core bx used for what?
uncertain FNA findings
what can core needle bx show that FNA can’t?
epithelial hyperplasia/malignancy b/c does histology
what is the method of choice for histologic dx?
core needle bx
tx for fibrocystic breast disease?
reassurance to pt, avoid impact sports, wear bra
APAP, NSAIDs
Aspiration of cyst (if isolated mass noted)
if pt is in significant discomfort with fibrocystic breast disease, what is the tx?
Tamoxifen (off-label use)
-hormone receptor drug
Danazol (FDA approved)
when does pt with fibrocystic breast disease need followup if isiolated mass noted with aspiration of cyst?
4-6 weeks later to re-assess, then few times/year
sx’s of fibrocystic breast disease will recur until when?
onset of menopause
fibroadenoma common in who?
young women (10-30 y/o)
if mass is detected in >30 y/o what must you rule out?
fibrocystic changes or cancer
when does fibroadenoma NOT occur after?
does not occur after menopause
sx’s of fibroadenoma?
have tumor-like findings
increase in size with pregnancy
regress after menopause
***painless/non-tender
***rubbery
is size of fibroadenoma related to menses?
NO!!!, but size can still change d/t hormones
etiology of fibroadenoma?
benign glandular tumor
dx of fibroadenoma?
US, mammogram, core bx
when do you excise fibroadenoma?
- Painful/Uncomfortable
- Becomes larger
- There’s malignancy on core biopsy
- If the patient is worried about not removing mass
how do you monitor fibroadenoma?
serial breast exams (clinical breast exam and self)
mammogram/US
ddx for fibroadenomas
fibrocystic
breast cancer
breast fat necrosis
breast mastitis
what can breast fat necrosis cause? difficult to distinguish from what?
a mass with nipple or skin retraction
difficult to distinguish from breast cancer
what is breast fat necrosis due to?
trauma including surgery, radiation therapy
dx and tx of breast fast necrosis?
dx = core bx
tx = excision is sometimes needed when dx is not clear
who does breast mastitis occur in?
BREAST FEEDING MOTHERS
offending organism in breast mastitis?
S. aureus
sx’s of breast mastitis?
Unilateral inflammation, erythema, mastalgia, sore nipple, engorged breast
Systemic symptoms (fever, chills)
tx of breast mastitis? abx?
Regular emptying of the breast - breast feeding or mechanical suction (KEEP BREAST FEEDING!!!)
Abx: dicloxacillin
complication of breast mastitis?
Abscess - will need to be aspirated or excised if present
etiology of nipple discharge?
- Normal lactation
- Benign physiologic nipple discharge
- Pathologic nipple discharge
what are benign physiologic nipple discharge causes? colors of discharge?
Galactorrhea í further workup with endocrine studies
White, clear, yellow, green, brown, gray, blue
what are pathologic nipple discharge causes?
Benign intraductal papillomas (MOST COMMON CAUSE)
Intraductal breast cancer
what drugs can cause galactorrhea and gynecomastia?
antipsychotics
when have pt with nipple discharge what exam should be performed?
complete breast exam of all 4 breast quadrants
also LNs:
- Subareolar area
- Axilla
- Supraclavicular
- Infraclavicular
what else needs to be assessed on PE for nipple discharge besides breast exam and LNs? elicit what?
skin changes for dimpling, edema, erythema, crusting of the nipple
elicit discharge
what LNs need to be assessed for nipple discharge?
- Subareolar area
- Axilla
- Supraclavicular
- Infraclavicular
sx’s of benign nipple discharge?
Provoked, bilateral, multiductal
sx’s of pathologic nipple discharge?
Unprovoked, unilateral, uniductal, blood/blood tinged discharge (sanguineous)
associated with breast mass
