Cellulitis -a diffuse inflammation of the deep dermal and subcutaneous tissue that results from an infectious process, characterized by erythema, warmth, and tenderness of the involved tissues (Ferri, 2018). This can occur anywhere in the body where there is any break in the skin. The skin and subcutaneous tissue respond to a bacterial infection by an inflammatory response; there’s an increase in vascular permeability of the microcirculation of the skin that allows protein-rich fluids to leak into the interstitial tissue causing inflammation (Dunphy et al., 2015). Vasodilation also occurs causing the erythema of the tissue involved. Leukocytes accumulate at the site of injury and engulf particulate material such as the bacteria, cellular debris, and antigen-antibody complexes. In most cases, bacterial burden in cellulitis is low unless there’s an abscess or skin ulcer is present (Dunphy et al., 2015).
