Chief complaint of “abscess.” Quick and dirty. Otherwise-healthy patient with a 4 cm abscess on the right thigh with no surrounding cellulitis. No IV drug use history. No significant co-morbidities, and no previous abscesses. Diagnosis: uncomplicated superficial cutaneous abscess (SCA). You know that antibiotics are probably not necessary after I & D. However, the patient complains of pain when you begin to pack it with iodoform gauze. He asks if packing is really necessary. Is it?
