A 29-year-old woman, who delivered a healthy infant four weeks ago, is evaluated for sudden-onset fever, chills, and left-sided breast pain. She has been exclusively breastfeeding since delivery. Her temperature is 38.4∘38.4^\circ C (101.1∘101.1^\circ F), blood pressure is 112/70112/70 mm Hg, and pulse is 9898/min. Physical examination of the left breast reveals a focal, wedge-shaped area of erythema, warmth, and induration in the upper outer quadrant that is markedly tender to palpation. There is no palpable fluctuance, skin retraction, or purulent nipple discharge. The right breast is unremarkable. Which of the following is the most appropriate next step in management?

  1. Initiate an oral antistaphylococcal antibiotic and encourage continued breastfeedingCevap
  2. B
    Initiate an oral antistaphylococcal antibiotic and advise cessation of breastfeeding from the affected side
  3. C
    Recommend supportive therapy with warm compresses and ibuprofen alone
  4. D
    Order a sonographic evaluation of the left breast
  5. E
    Refer for prompt incision and drainage of the affected breast quadrant

Cevap

Initiate an oral antistaphylococcal antibiotic and encourage continued breastfeeding
This patient's presentation of fever, focal breast erythema, warmth, and tenderness in the setting of lactation is highly characteristic of lactational mastitis. The most common causative organism is Staphylococcus aureus, which typically enters the breast tissue through microabrasions in the nipple. The standard of care is empiric oral antibiotic therapy targeting methicillin-susceptible S. aureus (such as dicloxacillin or cephalexin) combined with continuous, frequent milk drainage. Stopping breastfeeding is explicitly contraindicated, as inadequate breast emptying leads to milk stasis, which can exacerbate the infection and lead to abscess formation.

Adım Adım Çözüm

1
Analyze the patient's symptoms and physical exam findings.
The patient has fever, chills, and focal breast erythema/tenderness four weeks postpartum without any fluctuant mass.
These findings are classic for lactational mastitis, a localized soft tissue infection of the breast.
2
Identify the standard management for the suspected diagnosis.
Management includes systemic antibiotics to treat the underlying bacterial infection (usually Staphylococcus aureus) and continuous milk drainage.
Antibiotics are required due to systemic symptoms, and continuous breastfeeding prevents milk stasis, which is the primary driver of abscess formation.

Anahtar Kavram

Uncomplicated lactational mastitis is managed clinically with oral antistaphylococcal antibiotics (e.g., dicloxacillin, cephalexin) and the continuation of frequent milk drainage (via breastfeeding or pumping) to prevent progression to a breast abscess.
