Cellulitis is a skin infection affecting the connective tissue layer of the dermis.
Causes and Risk Factors
Cellulitis often follows breaches in the skin such as abrasions, lacerations, IV catheters, etc. It can take as little as 24 hours to develop.
The most common causes include S. pyogenes and Staph. aureus.

History
Physical Exam
Lab Investigations
Blood cultures should be carried out if sepsis is a potential concern.
Diagnostic Imaging
Pathophysiology
Treatments
Coverage of Staphylococcus often leads to the use of cloxacillin. If cellulitis is more severe, cloxacillin can be used in combination with penicillin or ampicillin.
IV antibiotics may be required in severe cases, along with tissue debridement if necessary.
Pain control should be provided with acetaminophen or ibuprofen.
Consequences and Course
Properly treated cellulitis will often resolve within a week. However, serious cases can take months to clear, or can lead to severe disability and death if sepsis develops.
Cellulitis can recur, especially if improperly treated.
