Case in brief
A 17-year-old female presented with a non-puerperal breast abscess following influenza A and the rupture of an epidermal cyst. Finegoldia magna was identified through anaerobic culture, alongside Staphylococcus simulans. Treatment involved systemic cefmetazole, ultrasound-guided debridement, and catheter placement for metronidazole irrigation. This approach led to rapid infection resolution and preserved breast aesthetics.
What made this case unusual
The case highlights Finegoldia magna as an opportunistic pathogen causing non-puerperal breast abscess in an adolescent, which is a rare occurrence.
Diagnostic / clinical pearl
Clinicians should consider Finegoldia magna in the differential diagnosis of non-puerperal breast abscesses, especially in adolescents with recent infections.
Why it matters
This case underscores the importance of integrating surgical and antimicrobial strategies in managing infections caused by biofilm-forming anaerobes.
