colloid (mucinous) carcinoma presetation
postmenopausal
slow growing
axillary metastases
slightly higher in BRCA1
most common regions for carcinoma
upper outer
sub areolar
4 molecular subtypes of carcinoma of breast
Laminal A
Luminal B (poorer prognosis)
HER2 psotive
Basal like (triple negative)

gynecomastia morpholgy
subareolar mass possible
periductal hyaline, collagenous tissue
epithelial hyperplasia of ducts
ductal carcnimoma in situ histopathoogical types
Comdeo
Non-comedo
(cribrifomr, micropapillary, papillary, solid, flat/clinging)
most important prognostic factor for invasive carcinoma in absence of distant metastases
axillary node status
Oncotype=
applicable for pt with early carcinoma, small, node negaative, ER+
expression of a set of genes predictsresponse to chemo
invasive lobular carcinoma microscopic features
small cells
single file pattern or targettoid pattern
no glands
intracytoplasmic mucin vacuoes
signet ring cells

metastasis pattern
often postmenopause,
multicentric
often contralateral carcinoma (previous or lateer)
metatases: CSF, serosal surfaces, GI, Ovary, uterus, bone marrow

medulalary carcinoma mutation
increased with BRCA1
does not overexpress Her2/Neu,
negative for ER/PR
