What is a defining feature of erysipelas?

Erysipelas is characterized by a bright red, swollen appearance of the skin, which is a result of a bacterial infection, typically caused by Streptococcus pyogenes. The affected area usually has a sharp, well-defined border, and the skin is often warm and tender to the touch. This striking redness and swelling is what helps to distinguish erysipelas from other skin conditions.

While honey-colored crusts on the skin are more indicative of impetigo, and pearly, raised lesions are characteristic of conditions like basal cell carcinoma, flat, rash-like lesions do not capture the distinct presentation of erysipelas either. Recognizing the bright red and swollen appearance is crucial for correct diagnosis and ensures appropriate treatment is initiated for this acute skin infection.
