Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Erysipelas is a group A streptococcal cellulitis (groups G, B, C, and D can be implicated as well as other bacteria causing an erysipelas-like infection) involving the skin; the infection is more superficial than cellulitis. The most affected sites are the face and the lower extremities. Sudden onset of fever, chills, and malaise is followed by the appearance of an erythematous, edematous, and painful plaque. The characteristic border is sharp and elevated. This nonpitting edematous plaque is different from typical cellulitis due to dilation of the superficial lymphatics. Regional lymphadenopathy and lymphangitis may be present. Patients with chronic lymphedema are prone to repeated infections.
