Erysipelas

What is Erysipelas

Erysipelas is due to S. pyogenes and is characterized by an abrupt onset of fiery-red swelling of the face or extremities. It particularly affects infants and the elderly, but can affect any age group. The distinctive features of erysipelas are well-defined indurated margins, particularly along the nasolabial fold, rapid progression, and intense pain. The affected skin is red, swollen and may be finely dimpled (like an orange skin). It may be blistered. Bleeding into the skin may cause purpura (purple patches). Flaccid bullae may develop during the second or third day of illness, but extension to deeper soft tissues is rare.

Treatment of Erysipelas

Treatment with penicillin is effective; swelling may progress despite appropriate treatment, though fever, pain, and the intense red color diminish. If you suspect erysipelas, you should always call your doctor. Desquamation of the involved skin occurs 5 to 10 days into the illness. Infants and elderly adults are most commonly afflicted, and the severity of systemic toxicity varies.
