Benign Breast Conditions Flashcards
(46 cards)
most common breast lesion
fibrocytic change
ill defined thickening/lumpiness of breast in female 40-55 yrs.
most likely?
fibrocytic change
microscopic appearance of fibrocystic change
combination of cyst formation, apocrine metaplasia, fibrosis, epithelial proliferation
describe the cysts in fibrocystic change
localised dilatation of lobular + terminal ductules
multiple + <1cm
thin walled
blue appearance on microscope
presentation of fibrocystic change
ill defined thickening/lumpiness
painless, firm, mobile mass in female <30
most likely?
fibroadenoma
pathology of fibroadenoma
localised hyperplasia – well defined mass
- proliferation of intralobular stroma
who is fibroadenoma common in
young females
more common in africans
what is a tubular adenoma
benign circumscribed lesion
similar presentation to fibroadenoma
who gets a tubular adenoma
30-40 year olds
40% related to pregnancy
what is a hamartoma
disordered collection of lobules, stroma + fat
presentation of hamartoma
well defined mass - often impalpable + detected by mammogram
can occur at any age but more common pre menopause
presentation of sclerosis adenosis
often detected by mammogram
but can present as pain, tenderness, lumpiness/thickening
sclerosis adenosis on mammogram
microcalcification - can be mistaken for invasive carcinoma
appearance of a radial scar on mammogram
spiculate mass
pathology of radial scar
central fibrous scarring + entrapped tubular structures
presentation of duct papilloma
nipple discharge - might be blood stained
describe a central duct papilloma
usually larger, single, occurs in main nipple ducts
describe a peripheral duct papilloma
smaller, multiple, associated with hyperplasia
– increased risk of carcinoma
presentation of phyllodes tumour
fast growing, unilateral well defined mass.
middle aged-elderly females
microscopic appearance of phyllodes tumour
‘leaf like’ clefts of epithelium
most common organism in acute pyogenic mastitis
staph aureus
most common cause of acute pyogenic mastitis
lactation – infection via ducts/abrasion of the nipple
Tx of acute pyogenic mastitis
send them home with hot compress + encourage breast feeding
give flucloxacillin if not improved with 24 hours
percutaneous drainage if abscess
