Treatment of Superficial Breast Abscess

Initial Management

Incision and drainage (I&D) is the cornerstone of treatment for superficial breast abscesses, involving opening the abscess, evacuating the infected material, and continuing dressing changes until the wound heals by secondary intention, as recommended by the Infectious Diseases Society of America 1, 2
For simple abscesses with minimal surrounding erythema (<5 cm) and minimal systemic signs of infection (temperature <38.5°C, pulse <100 beats/min), antibiotics are unnecessary, according to the Clinical Infectious Diseases guidelines 1, 3
Cultures of the abscess material should be obtained during drainage to guide therapy if antibiotics become necessary, as suggested by the Clinical Infectious Diseases journal 2

Antibiotics should be added to I&D only if specific criteria are met, including presence of systemic inflammatory response syndrome (SIRS), erythema extending >5 cm beyond the wound margins, immunocompromised patient, or incomplete source control after drainage, as recommended by the Clinical Infectious Diseases guidelines 1, 2, 3
If antibiotics are indicated, empiric therapy should target Staphylococcus aureus (including MRSA consideration) and streptococcal species, which are the most common pathogens in breast abscesses, according to the Clinical Infectious Diseases journal 1, 2

Prescribing antibiotics for simple abscesses when not indicated provides no clinical benefit and contributes to antibiotic resistance, as warned by the Clinical Infectious Diseases guidelines and the Praxis Medical Insights 1, 3

For large abscesses, consider multiple counter incisions rather than a single long incision to prevent step-off deformity and delayed wound healing, as suggested by the Praxis Medical Insights 3
If the patient has significant systemic symptoms, consider hospital admission for intravenous antibiotics and more aggressive management, according to the Clinical Infectious Diseases journal and the Praxis Medical Insights 2, 3
For recurrent abscesses, evaluate for underlying conditions such as hidradenitis suppurativa or foreign material, as recommended by the Clinical Infectious Diseases journal 2
