Causes
Cellulitis is caused by bacteria entering the body by way of a break in the skin. This break need not be visible. Group A streptococcus and staphylococcus [1] are the most common causative agents of cellulitis. These bacteria are part of the normal flora living on the skin but they will cause infection if the skin is broken. Predisposing conditions for cellulitis include insect bites, animal bites, pruritic skin rash, recent surgery, athlete's foot, dry skin, eczema, burns and boils. Another cause may be Hemophilus influenza, especially in cases of facial infections.[2]
The appearance of the skin is used by a doctor to make a diagnosis. The doctor may suggest blood tests, a wound culture, or other tests to rule out deep vein thrombosis. Cellulitis in the lower leg is characterized by signs and symptoms that may be similar to deep vein thrombosis such as warmth, pain and swelling.
In rare cases, the infection causing cellulitis can spread to the deep layer of tissue called the fascial lining. Necrotizing fasciitis, also called "flesh-eating disease" by the media, is an example of a deep-layer infection. It represents an extreme medical emergency.
