4 groups of diseases of breast**
diagnostic tests for breast (3)**
acute mastitis pathogenesis
proliferation of staphs in milk
treatment of breast abscess (3 steps)
idiopathic granulomatous mastitis
inflammatory disease (rare) parous women (given birth)
TB (granulomatous inflammation)
treatment of idiopathic granulomatous mastitis (3)
steroids
immunosuppressives
surgery
breast augmentation causes (3)
breast augmentation (paraffin injections) complications \+ micro characteristics
paraffinoma
- multinucleate giant cell rxn
fibrocystic change (FCC)
benign epithelial breast lesion
(CASE)
- **stromal sclerosis/ fibroadenomatoid change,
cystic dilation of ducts,
epithelial hyperplasia,
apocrine metaplasia (breast epithelial cells -> sweat glandular cells)
histological classification of breast neoplasms (8)**
fibroadenoma
benign fibroepithelial tumour
young women (25yrs)
firm, well defined lump
proliferation of glandular and stromal elements, circumscribed and uniform
can recur/regress
phyllodes tumour
fibroepithelial
leaflike architecture. not well circumscribed - some parts enter adjacent tissue
risk of malignancy (higher than fibroadenoma)
risk factors of breast cancers (6)**
clinical presentation of breast cancers (5)**
non-invasive malignant epithelial carcinomas of breast (5 types)
in-situ cancer vs
invasive cancer vs
metastatic cancer
DCIS presentation (5)
Incidental finding Mammographic density Nipple discharge Paget’s disease Palpable mass
LCIS presentation
Incidental finding
not associated with calcifications or stromal desmoplastic reactions that produce mammographic densities
location: DCIS vs LCIS
DCIS: ducts
LCIS: lobules
(based on their name DUH)
cell size: DCIS vs LCIS
DCIS: medium/large
LCIS: Small
histological subtypes: DCIS vs LCIS
DCIS: - Comedo (prominent apoptotic cell death and has greater malignant potential - cribriform - solid - papillary - micropapillary LCIS: - solid
presence of calcifications: DCIS vs LCIS
DCIS: may be present
LCIS: absent
Risk of subsequent invasive breast cancer + location: DCIS vs LCIS
DCIS: higher risk. ipsilateral invasion -> increases risk of invasice carcinoma by 10 times
LCIS: lower risk. can be ipsilateral/contralateral
