Highlights & Basics
- Cellulitis and erysipelas can usually be diagnosed based on history and examination only, although blood cultures and microscopic examination of cutaneous aspirates, biopsies, or swabs should be considered for selected patients, including those who are immunocompromised.
- Prior episodes, preexisting lymphedema or venous insufficiency, diabetes, obesity, and tinea pedis can all predispose to cellulitis.
- Antibiotics targeted at the most common etiologies (streptococci and Staphylococcus aureus) usually result in resolution.
