This patient had impetigo. The honey crusted erythematous lesions are typical for this superficial bacterial skin infection. Impetigo is caused by Staphylococcus aureus and/or group A beta-hemolytic Streptococcus (GABHS). The differential diagnosis for this case included herpes simplex, tinea corporis, and superinfected atopic dermatitis.
There is good evidence that topical mupirocin is equally or more effective than oral treatment for people with limited impetigo. Mupirocin also covers methicillin-resistant Staphylococcus aureus. Extensive impetigo should be treated for at least 7 days with antibiotics that cover group A beta-hemolytic Streptococcus and S aureus.
We treated our patient with oral cephalexin 35 mg/kg/day and the impetigo was resolved at a 2-week follow-up visit. The culture grew out S aureus sensitive to cephalosporins.
