Which treatment is appropriate for a subpectoral abscess?

• A. I&D along lateral border of pectoralis major muscle plus systemic antibiotics
• B. Oral antibiotics only
• C. Observation without drainage
• D. Needle aspiration without antibiotics

Answer: (A)

A subpectoral abscess is a pus-filled collection deep beneath the pectoralis major that needs surgical drainage in addition to antibiotics. The reason drainage is essential is that antibiotics alone do not reliably penetrate an established abscess cavity, and removing the purulent material is critical to terminate the infection and prevent spread or persistence. The preferred approach—incision and drainage along the lateral border of the pectoralis major—provides direct access to the subpectoral space while avoiding breast tissue and important nearby structures. This route allows thorough evacuation of pus, helps collapse the cavity, and often permits placement of a drain to prevent reaccumulation. After drainage, systemic antibiotics are started to treat surrounding cellulitis and any additional organisms, with culture results guiding therapy. Oral antibiotics alone, observation without drainage, and needle aspiration without antibiotics are inadequate for a subpectoral abscess because they fail to remove the infected material, risking ongoing infection and complications.
