An erysipelas skin lesion typically has a raised border that is sharply demarcated from normal skin. The underlying skin is painful, intensely red, hardened (indurated), swollen, and warm.
Facial erysipelas lesions classically involve the cheeks and the bridge of the nose.
The diagnosis of erysipelas is based on the characteristic appearance of the skin lesion. Skin biopsies are usually not needed. Blood cultures are rarely positive (up to 5% of the time).
