What is Lactational Breast Abscess?

Acute infection with localized purulent collection in mammary tissue during lactation.

Most common pathogen: Staphylococcus aureus (including MRSA in 50% of cases).

Develops as complication of unresolved or inadequately treated puerperal mastitis (3-11% progress to abscess).

Usually unilateral, often peripheral, occasionally subareolar.

Symptoms

Painful, hot, fluctuant mass in the breast.
Erythema and induration of overlying skin.
Fever (>38.5°C), chills, malaise.
Tachycardia, leukocytosis, elevated CRP.
Purulent or blood-tinged nipple discharge.
Reduced milk flow from affected side.
Axillary lymphadenopathy.

Risk Factors

Inadequate or delayed treatment of mastitis.
Improper breastfeeding technique, nipple cracks/fissures.
Engorgement, blocked ducts, prolonged feeding intervals.
Maternal smoking (3-fold risk), diabetes, immunosuppression.
Primiparous mothers, age >30 years.
S. aureus nasal colonization.

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Worsening breast pain despite mastitis treatment.
  • Palpable fluctuant mass.
  • Persistent fever >48-72 hours on antibiotics.
  • Significantly red, hot, fluctuant area.
  • Suspicion of MRSA (recurrent infection).

Treatment Methods

01
Imaging: breast ultrasound (gold standard, also guides drainage).
02
First-line: ultrasound-guided needle aspiration with culture, repeated as needed (success 80-90% in <3 cm).
03
Larger or recurrent abscesses: percutaneous catheter drainage.
04
Surgical incision and drainage if conservative measures fail.
05
Empiric antibiotics: dicloxacillin/cefazolin (MSSA) or clindamycin/TMP-SMX/vancomycin (MRSA risk).
06
Continue breastfeeding from affected side (safe and beneficial); pump if too painful.
07
Pain control: NSAIDs, warm compresses, breast support.
08
Lactation consultant referral; treat underlying mastitis cause.
09
Follow-up to confirm resolution; biopsy if mass persists (rule out inflammatory carcinoma).
