A 30-year-old male visited Primary Care for evaluation of a perioral sore. There was no history of herpes simplex virus infection and no report of any prodromal tingling symptoms. The sores were treated as impetigo. Impetigo is a common, highly contagious superficial infection that most commonly affects children. It can also affect adults, especially at sites of minor trauma or skin irritation. Impetigo is usually caused by Staphylococcus aureus infection, and is classified as bullous or nonbullous. This patient had nonbullous impetigo, which is more common in adults and presents as thin-walled vesicles that eventually break down and form a honey-colored crust. Such lesions should be cultured and treated with appropriate topical antibiotic ointments. If there is no response to topical medication, or if there is extensive surface area involved, oral antibiotics are indicated.
