A superficial infection of skin secondary to either S. aureus or group A β-hemolytic streptococci. The primary lesion is a superficial pustule that ruptures and forms a “honey-colored” crust. Tense bullae are associated with S. aureus infections (bullous impetigo). Lesions may occur anywhere but commonly involve the face. Impetigo and furunculosis (painful erythematous nodule, or boil) have gained prominence because of increasing incidence of CA-MRSA.
Gentle debridement of adherent crusts with soaks and topical antibiotics; appropriate oral antibiotics depending on organism.
