Pathophysiology

Most cases of erysipelas are due to Streptococcus pyogenes (also known as group A streptococci), although non-group A streptococci can also be the causative agent. Historically, the face was most affected; today the legs are affected most often.

Erysipelas infections can enter the skin through minor trauma, eczema, surgical incisions and ulcers, and often originate from strep bacteria in the subject's own nasal passages.
