What is the pathophysiology of cellulitis on diagram presentation?

Answer 1

Cellulitis is an acute bacterial skin infection characterized by inflammation of the dermis and subcutaneous tissue. It typically occurs when bacteria, often Streptococcus or Staphylococcus, enter through breaks in the skin, leading to localized immune responses that cause redness, swelling, warmth, and pain. On a diagram, you might see an area of affected skin displaying these features, along with the underlying inflammatory response including edema, dilation of blood vessels, and infiltration of immune cells. The diagram may also illustrate the spread of bacteria along tissue planes, highlighting the potential for systemic involvement if not treated promptly.
