|
|
periductal mastitis: aka? who do we see it in? how do they present?
|
aka subareolar abscess
SMOKERS (male and female) NOT assoc with lactation present: painful, erythematous subareolar mass; may have drainage out of fistula formed at edge of areolar tissue |
|
|
describe periductal mastitis
|
squamous metaplasia: (RECURRENT) glandular, columnar epithelium replaced by thick, keratinized squamous epithelium
abscess can form from rupture of blocked duct and inflamm resp to keratin; also fistula |

|
morphology of mammary duct ectasia
|
ectasia= dilation
dilated ducts inspissated discharge chronic granulomatous inflamm and fibrosis |

|
history of trauma or prior surgery
painless, palpable mass, with skin RETRACTION *mimic CA |
|
|
morphology of Fat necrosis
|
inflamm due to rel of "foreign" lipid after trauma
firm tissue w/ small foci of chalky white, hemorrhagic debris surr by foamy histiocytes and PMNs multinucleated giant cells, incr vascularization, fibroblasts to wall off |
