Impetigo

• Superficial skin and soft tissue infection of childhood most often caused by Streptococcus pyogenes and Staphylococcus aureus
• Also known as pyoderma or impetigo contagiosa
• Peak age 2 to 5 years, but can occur in adults
• An initial papule turns into a vesicle surrounded by erythema, typically on exposed skin
• The lesions become pustules, which rupture and form crusted lesions
• If deeply ulcerated, it's called ecthyma
