These infections often occur following a break in normal skin integrity from either trauma or skin disease (e.g., atopic dermatitis). The vast majority of these infections are caused by Staphylococcus aureus and Streptococcus pyogenes (Table 77–1). Rarely, infections in patients with burns, diabetes mellitus, or decubitus ulcers may involve gram-negative rods such as Pseudomonas or anaerobes. Hematogenous seeding of organisms into the skin can occur but is uncommon. Normal histology of the skin can be seen in Figure 77–1.
