1

def

localised area of infection with a walled-off collection of pus in the breast tissue
may or may not be associated with mastitis

2

what are the two main forms of breast abscesses

1 peurperal (lactational)
2 non-peurperal

3

aetiology

1 peurperal (lactational)
-milk stasis is associated with infection
-infection (s. aureus, coagulase negative staphylococci)
2 non-peurperal
-s. aureus + anaerobes (enterococci)
-smoking
-mammary duct ectasia/periductal mastitis
-associated with wound infections after surgery, diabetes

4

epi

breast abscesses develops in 3-11% of women with mastitis
lactational breast abscesses are common, and often start after breast-feeding or weaning
non-lactational breast abscesses are common in 30-60yrs smokers

5

history

1 discomfort + painful swelling in breast
2 malaise + fever

6

what do women with a non-peurperal abscess have a history of

previous infections

7

examination

local area
-area of breast is swollen, warm and tender
-in non-peurperal cases there may be evidence of scars or tissue distortion from previous episodes, or signs of duct ectasia (nipple retraction)

8

investigations

1 clinical examination
2 USS
3 aspiration for microscopy, culture + sensitivity

9

management

medical
-antibiotics
-regular breast drainage in lactational abscesses to prevent milk stasis
surgical
-lactational: daily needle aspiration with antibiotics for small abscesses, incision and drainage is required for larger abscesses

10

management for non-peurperal abscesses

the definitive treatment involves antibiotics to first control the infection and then excision of the involved duct system

11

what antibiotics are used for lactational abscesses

flucloxacillin

12

what antibiotics are used for non-peurperal abscesses

flucloxacillin + metronidazole

13

complications

slow wound healing
difficulties breast feeding
poor cosmetic outcome

14

prognosis

if untreated breast abscesses can discharge
non-peurperal abscesses often recur
