Cellulitis syndromes: an update.

Cellulitis is a commonly seen clinical syndrome that is most often associated with beta-haemolytic streptococci and Staphylococcus aureus. Several medical conditions and a variety of procedures can predispose to the development of cellulitis by a common mechanism: venous and lymphatic compromise. The precise pathophysiologic and immunologic details involved in the predisposition to cellulitis remain poorly understood. Therapy is directed at resolution of acute infection and prevention of recurrent episodes of cellulitis.
