PY - 2019 T2 - Fitzpatrick's Dermatology, 9e AB - AT-A-GLANCECommon infection of the deep dermis and subcutaneous tissue most often caused by streptococcal and staphylococcal species, resulting in erythema, swelling, warmth, and pain of the affected site.Unilateral lower-extremity involvement is typical and systemic symptoms are usually absent.Important local risk factors include compromise of the skin barrier or underlying lymphovascular system.Diagnosis is most often made clinically because of frequently equivocal or negative workups.Treatment consists of antibiotics, but multiple recurrences may be observed.Common variants:Erysipelas: sharply demarcated, bright red, edematous plaques resulting from superficial lymphatic infiltration.Purulent cellulitis: localized pustules or abscesses associated with cellulitis.
