Mastalgia
Etiology
classifications: cyclical, non and extra mammary
Mastalgia Etiology
- mastaliga = breast pain
- can be realted to breast cancer but very uncommon
Classifications of Mastalgia
- cyclical: related to the hormonal cycles of the period& ovulation : bilateral pain thats cyclical
- Noncyclical: occuing not in releation to the cyce
- Extra Mammart: pain which is in the areas but not a result of the breast itself (Example: chest wall pain)
Possible Reasons for Noncyclical mastalgia
large pendulous (hanging breasts = pain)
diet, lifestyle related (smoking and high fat)
horome replacement thearpy
cysts (creating discomfoty)
Ductal Ectasis (inflammaion, not an infection of the ducts)
Mastitis
iflammatory BC
Hidradentisi supperativa
Workup and Evalauation of Mastalgia
- rule out mastitis (reddness, fever, etc.)
- rule out breast cancer (masses, skin change, bloody discharge)
- rule out chest wall as the pain souce (extra mammary)
Focal Breast Pain
- a little sus for BC : get US/mamo.
Diffuse Breast Pain
- not BC or worried about it
- supportive treatment, bras, NSAIDS, HRT changes, contraceptive changes
- 6 months without relief: tamoxifen
Galactorrhea
Etiology
Causes
Symptoms
Etiology
- milk secretion from the breast in a non-breast feeding women
- physiologic nipple discharge
- can be due to stress or nipple stimulation
Symptoms
- non-bloody bilateral discharge
females : premenopausal
- hypogonadism: infertility, oligomenorrhea or amennorrhea
- low BMD
Males
- decrese libiod
- impotence
- gynecomastia
Causes
- most often caused by hyperprolactinemia which can be secondary to
- medications
- endocrine tumors (pituitary adenomas)
- endocrine abnormalities
(rearely)
- idopathc
- hypothyroid
- chest wall injury
- chronic renal failure
- estrogen administeration
Galactorrhea
Work Up
Treatment
Work up
- pregnancy test
- prolactin levels
- creatinine (for renal)
- TSH
if any of the above = abnormal, refer to endocrine
Treatment of Galactorrhea : depends on cause
- Dopamine Agonist cabergoline (because decreased Dopamine increased proactin; so increasing dopamine will decrease prolactin)
- ovulation induction
- surgery (if pituriaty adenoma)
- gondal steroid replacement (if needed)
Symptoms of pathologic nipple discharge
Symptoms
- unilateral
- involving one duct
- spontaneous
- persistant
- serous or serosanguineous(blood tinged) fluid
- associated with masses or skin changes
can be due to papilloma, duct ectasia, infection or cancer
Papilloma
Etiology
Diagnosis
Treatment
Etiology
- MCC of pathologic nipple discharge
- benging tumor which grows within the lining of the breast duct
- due to HPV in 70% of cases
- can harbor atypia and DCIS (if solidary tumor) : rule this out via imaging/biopsy
Diagnosis
- clinically made
- if sus for malignancy: can do biopsy and imaging
Treatment
- surgical removal
Duct Ectasia
Etiology
Symptoms
Diagnosis
Treatment
Duct Ectasia : Etiology
- benign condition of breast duct wall thickening and widening which leads to blockage and fluid build up
- common in pre-menopausal women
Symptoms
- discharge: sticky and thick
- can be assocaited with nipple changes, skin changes and masses (sccar tissue around the duct = mass)
Diangosis
- rule out cancer and infection (if needed via imaging and biopsy)
Treatment
- no treatment needed; usually resolves on own
- can be surgically removed
Gynecomastia
Etiology & causes
Evaulation
Etiology
- enlargement of the breast tissue in men
Causes
- persistant pubertal gynecomastia
- drugs
- idopathic
- cirrhosis/malnutrtion
- male hypogondaims
- testicualr tumor
- hyperthyroid (increased ratio of estrogen:androgens)
- chronic kidney disease
Evaluation
- need to do a through evaluation of the breast in men to ensure its not breast cancer!!: exam
- Gynecomastia: rubbery-to-firm, cocentric disk of tissue, moblie and loacted directly beneath the areoa area
- masses assocaited with cancer: will be eccentrically positioned
Labs
- testosterone (eval. hypogonad), LH, Estrogen, HcG (germ cell CA)
Treatment
- observation
- withdraw any agents (like meds) if causes
- treat underlying issues
- tamoxifen can be used for idopathic
- surgery
Fibroadenoma
Etiology
Symptoms
Diagnosis
Etiology
- most common benging tumor in the breast
- single, benign tumor with glandual and fibrous tissue
- possibly due to hormones; common in reproductive yeras, enlarge with pregnancy and estrogen therapy
Symptoms : mass characterisitcs
- typically oval or round
- rubbery and discrete
- non tender
- moblie
- accidental finding
Diagosis
- US, mammogram, MR (to r/o cancer and infection)
- biopsy: FNA/core needle or excisional/incisional
Fiberoadenoma
Surgical Indications
Surgical Indications of a fiberoadenoma
- large size > 2.5 cm
- causing discomfort or deformity
- age > 35 (cancer concern)
- immoblie or poorly circumscribed
- patitent desire
- indeterminate biopsy
Fibrocystic Changes of Breast Masses
general clinical symptoms of these
evaluation: waht are your options
general clinical symptoms
- masses: asymptomaticor can be painful/tender
- can fluctuate with menstrual cycle
- can be bilateral
- can be associated with serous nipple discharge
Evaluation
- for those < 40 y/o = US sufficient
- for those > 40 y/o = mammogram
- aspiration: if mass is cyst-like
- biopsy
Fiberocystic Changes in Breasts
Aspiration protocol
when to send for cytology
what to do if recurred 2nd or 3rd
Aspiration
when to send aspiration for cytology
- turbid or grossly bloody fluid
- only minial fluidobtained
- the mass remains after its been aspirated
Follow up 4-8 weeks
- if the cyst is no longer palpable = benign
- aspirate and send for cytology if it recurred; regardless of fluid appearance; need to assess
a third recurrance/persistant mass warrents a biopsy even if cytology came back negative
