Diagnosis can usually be made on history and examination only, although purulent focus culture and molecular diagnostic procedures should be performed if cellulitis is associated with a wound or pustular focus.
Prior episodes of cellulitis, preexisting lymphedema or venous insufficiency, and tinea pedis can all predispose to this condition.
Antibiotics targeted at the most common etiologies (streptococci and Staphylococcus aureus ) usually result in resolution.
Cellulitis is an acute spreading infection of the skin with visually indistinct borders that principally involves the dermis and subcutaneous tissue. It is characterized by erythema, edema, warmth, and tenderness, and commonly occurs in an extremity.
Erysipelas is a distinct form of superficial cellulitis with notable lymphatic involvement and is raised, sharply demarcating it from uninvolved skin.
