Erysipelas Superficial Skin Infection

Erysipelas is an acute, nonpurulent bacterial infection of the upper dermis and superficial dermal lymphatics. Group A Streptococcus—most often Streptococcus pyogenes—is the usual cause. The infection commonly enters through a small breach such as a fissure between the toes, macerated skin, eczema, a venous ulcer, or a surgical or lymphedematous skin change. The superficial location gives erysipelas its classic appearance: a bright, warm, tender area with a raised, sharply defined edge. Cellulitis extends farther into the deeper dermis and subcutaneous tissue, so its border is usually less distinct. The practical-nurse priority is to recognize this pattern, identify factors that permit recurrence, monitor for systemic deterioration, implement the prescribed plan, and promptly report changes to the supervising RN or authorized provider.
