Answer

Today, erysipelas is a relatively rare acute streptococcal infection involving the deeper layers of the skin and the underlying connective tissue. Skin over the affected area tends to be swollen, red, and exquisitely tender, unlike in streptococcal impetigo, which is usually painless. Superficial blebs may be present. The most characteristic finding in erysipelas, the sharply defined and slightly elevated border, helps to differentiate this entity from cellulitis, which has an indistinct border.
