Forms Of Impetigo
The dermatologists with Advanced Dermatology and Skin Cancer Center create individual treatment plans for the three common forms of impetigo.
Ordinary Impetigo: Caused by Streptococcal bacteria, ordinary impetigo appears as red sores that rupture quickly. The sores ooze fluid that forms a honey-colored crust. Ordinary impetigo is common in children from infancy to age two.
Bullous Impetigo: This form of impetigo features fluid-filled blisters caused by Staphylococcus bacteria. Bullous impetigo is contagious and is spread by coming into contact with the fluid from a broken blister.
Ecthyma: Ecthyma is the most serious form of impetigo. It penetrates to the dermis — the second layer of skin — and is characterized by painful, fluid- or pus-filled sores. Ecthyma lesions are usually found on the feet or legs. As the sores break open, hard yellow-gray crust forms. Patients may have swollen lymph glands in the affected areas.
Treatment usually includes seven days to 10 days of oral and/or topical antibiotics. Completing the full course of antibiotics is crucial to full healing of the sores. Over-the-counter topical antibiotics, such as Neosporin, aren't effective.
