Common skin and soft tissue infections covered in this chapter include impetigo, folliculitis, furuncles, carbuncles, cellulitis, and necrotizing fasciitis. Impetigo is a superficial pustular skin infection. Multiple lesions occur on exposed skin of the face and extremities. Staphylococcus aureus causes most cases. Folliculitis is a superficial skin infection of hair follicles. A furuncle is a purulent, painful nodular skin infection involving the hair follicle that is usually a complication of folliculitis. A carbuncle is a cluster of abscesses in subcutaneous tissue that drain through hair follicles. The prevailing pathogen for both furuncles and carbuncles is S aureus. Skin abscesses involve the dermis and deeper skin tissues. Often a pustule is present on the skin. For most cases the pathogen is S aureus. Cellulitis involves skin and subcutaneous tissues. Clinical manifestations of cellulitis include swelling, erythema, tenderness, and warmth. Necrotizing forms of cellulitis are necrotizing fasciitis types I and II. Clinical features include fulminant destruction of tissue and systemic toxicity.
