Erysipelas is an infection of the upper layers of the skin (superficial). The most common cause is group A streptococcal bacteria, especially Streptococcus pyogenes. Erysipelas results in a fiery red rash with raised edges that can easily be distinguished from the skin around it. The affected skin may be warm to the touch. At one time, erysipelas was thought to affect mostly the face, but recent studies suggest that the distribution of the inflammation is changing since at the present time the legs are involved in almost 80% of cases. The rash may also appear on the arms or trunk.
Erysipelas begins with minor trauma, such as a bruise, burn, wound, or incision. When the rash appears on the trunk, arms, or legs, it is usually at the site of a surgical incision or a wound.
Erysipelas usually first appears as a localized lesion that is tender and red. The lesion quickly develops a bright red, shiny color and a spreading, raised border. The typical lesion is so characteristic that its presence is diagnostic. The lesion may feel hot and be painful. There may be accompanying high fever, chills, headache, nausea, and a general feeling of ill health (malaise). The skin in the affected area may resemble the peel of an orange.
In infants, erysipelas may appear on the abdomen due to infection of the umbilical cord. In children and adults, erysipelas most commonly develops on the legs, arms and face. Erysipelas may also develop at sites of minor surgery or trauma, or it may be due to lymphatic obstruction.
Erysipelas is caused by one of several strains of streptococcus bacteria, or less frequently by a staphylococcus infection. Streptococci are involved in about 80% of cases.
Erysipelas is a fairly common infection that may affect anyone at any age. It is most common in infants, young children and the elderly, including adults of either sex between ages 60 and 80.
The treatment of choice is penicillin. For the penicillin-allergic patient, erythromycin or cephalexin may be used.

The French Erysipelas Study Group, headquartered at a major teaching hospital in Reims, France, reported recently the results of a multi-center, randomized, controlled, clinical trial of a new treatment for erysipelas involving the drug pristinamycin. The group is studying whether pristinamycin might replace oral penicillin as the drug of choice to treat this disorder.
The results of these trials are being debated among clinical researchers interested in the treatment of this disorder.
