Patient Stories
A young woman presented to the office with a 3-day history of an uncomfortable rash on her lip and chin (Figure 116-1). She denied any trauma or previous history of oral herpes. This case of impetigo resolved quickly with oral cephalexin.
An 11-year-old-child presented with a 5-day history of a skin lesion that started after a hiking trip (Figure 116-2). This episode of bullous impetigo was found to be secondary to methicillin-resistant Staphylococcus aureus (MRSA). The lesion was rapidly progressive and was developing a surrounding cellulitis. She was admitted to a hospital and treated with intravenous clindamycin with good results.1
