Ecthyma is a skin infection similar to impetigo. It is often called "deep impetigo" because it occurs deep inside the skin.
Ecthyma is most often caused by the bacteria streptococcus. Sometimes, staphylococcus bacteria causes this skin infection.
The infection may start in skin that has been injured due to a scratch or insect bite. It often develops on the legs.
