Ecthyma is a bacterial skin infection caused by streptococcal or staphylococcal organisms.
Streptococcal and staphylococcal bacteria may cause skin infections at various levels and depths. Ecthyma is similar to impetigo, but causes deeper erosions of the skin. The infection may start at the site of a bug bite or scratch.
The streptococcal organism most often causes ecthyma. Any trauma or break in the skin allows the bacteria to begin growing.
Ecthyma begins as a small blister that may be pus-filled and have a reddish border. A crusted ulcer follows the appearance of the blister.
The healthcare professional is usually able to diagnose ecthyma after a complete history and physical examination. A culture may be done of the lesion.
Any injury or bite should be thoroughly cleansed. A person should avoid scratching any bites.
Long-term effects of ecthyma include spread of infection to other parts of the body and permanent skin damage with scarring.
Because ecthyma is a bacterial disease, it can be contagious to other people who come in physical contact with the infected person.
Antibiotics may be prescribed for ecthyma. Warm soaks are helpful to remove crusts from the lesions. Antiseptic soap or peroxide washes may help reduce the infection.
Side effects of antibiotics include stomach upset and allergic reactions.
Most people with ecthyma make a full recovery after treatment.
Any new or worsening symptoms should be reported to the healthcare provider.
