Ecthyma is a skin infection similar to impetigo. It is often called “deep impetigo” because it occurs deep inside the skin. Ecthyma extends into the dermis. Ecthyma is most often caused by the bacteria streptococcus.
The lesion looks like small blister with a red border that may be filled with pus. The blister is similar to that seen in persons with impetigo, but the infection spreads much deeper into the skin. There is permanent skin damage with scarring in case of Ecthyma.Treatment consists of local and systemic Antibiotics.
