48. Inflammations and fibrocystic changes of the breast, fibroepithelial tumors Flashcards
48-1. inflammation of breast
types of breast inflammation (4)
acute mastitis
periductal mastitis
mammary duct ectasia
fat necrosis
48-1. inflammation of breast
etiology of acute mastitis
bacterial infection (staphylococcus aureus), usually due to breast feeding
48-1. inflammation of breast
clinical symptoms of acute mastitis (3)
erythematous breast
purulent discharge
abscess
48-1. inflammation of breast
etiology of periductal mastitis
common in smoker
vitamin A deficiency, cause squamous metaplasia -> blocking
48-1. inflammation of breast
manifestation of periductal mastitis (2)
subareolar mass
nipple retraction
48-1. inflammation of breast
manifestation of mammary duct ectasia (3)
periareolar mass
retraction of nipple
green brown discharge
48-1. inflammation of breast
etiology of fat necrosis
trauma
48-1. inflammation of breast
manifestation of fat necrosis (2)
mass on physical exam
calcification on mammography
48-2. fibrocystic change of the breast
epidemiology, site of fibrocystic change
30-50 years old women
usually in upper outer quadrant
48-2. fibrocystic change of the breast
types of fibrocystic changes of breast
non proliferative - cystic metaplasia - fibrosis metaplasia proliferative - ductal hyperplasia - sclerosing adenosis - atypical hyperplasia
48-2. fibrocystic change of the breast
risk of malignancy
no risk : cyst metaplasia, fibrosis metaplasia
x2 risk : ductal hyperplasia, sclerosing adenosis
x5 risk : atypical hyperplasia
48-3. fibroepithelial tumor
subtypes of fibroepithelial tumor (3)
intraductal papilloma
fibroadenoma
phyllodes tumor
48-3. fibroepithelial tumor
morphology of intraductal papilloma
fibrovascular projection into the duct
48-3. fibroepithelial tumor
clinical manifestation of intraductal papilloma
bloody discharge
48-3. fibroepithelial tumor
differentiation between intraductal papilloma vs. papillary carcinoma
intraductal papilloma : epithelial cell + myoepithelial cell (2 lines)
papillary carcinoma : epithelial cell without myoepithelial cell (1 line)
