This section talks about skin and soft tissue infections and presents case studies relating to this subject. The resistance of skin to infection is due to the integrity of the keratinized skin, the presence of inhibitory fatty acids produced by sebaceous glands, the dryness of the skin, and the inhibitory effect of the resident normal skin flora. Skin and soft tissue infections can be caused by either direct penetration of a pathogen through the skin or hematogenous spread of the pathogen to the site. In the setting of severe damage to the skin, as occurs with burns, even normally innocuous organisms, including endogenous bacteria, can cause severe disease. Similarly, when the skin is no longer dry, as may occur in moist intertriginous spaces or when occlusive dressings are present, the patient is at increased risk of infection. The characteristic rash of Lyme disease, erythema migrans, is specific enough to establish the diagnosis. The nature of the lesion (macular, papular, vesicular, pustular, or bullous) may help to narrow the differential diagnosis. Skin and soft tissue infections can be classified on the basis of the anatomic level at which infection occurs. The more superficial infections, such as folliculitis caused by Staphylococcus aureus or cellulitis caused by S. pyogenes, are important to treat at an early stage. Important agents of skin and soft tissue infection are finally listed in the chapter.
