It is important to differentiate cellulitis from thrombophlebitis, contact dermatitis, drug reactions, and arthritis. Additionally, it should be differentiated from other causes of lower limb edema such as venous insufficiency and deep venous thrombosis.

Epidemiology and Demographics

Cellulitis is most frequently seen in middle-aged and older adults. It has an incidence of 200 per 100,000 patient-years with a higher incidence in males.

Risk Factors

The risk factors for cellulitis include, but are not limited to, the elderly, a weakened immune system, diabetes, HIV, prior history of cellulitis, varicose veins, skin disorders resulting in breaks in the skin, lymphedema, and hygiene.

Natural History, Complications and Prognosis

Trauma to the skin serves as an entry point for the bacteria, releasing toxins that produce an inflammatory response. This subsides with 7-10 days of antibiotic use. However, if not treated promptly with antibiotics, the disease spreads rapidly resulting in complications. These include sepsis, osteomyelitis, lymphangitis, endocarditis, meningitis, and gangrene.

Patients who require hospitalization for ICU admission, operating room surgical intervention, or death have one of the following six risk factors upon presentation[1]:

  • abnormal cross-sectional imaging result ("air or gas, abscess or fluid collection, osteomyelitis, or suspicion of osteomyelitis")
  • systemic inflammatory response syndrome
  • previous infection at the same location
  • infection involving the hand * diabetes* age >65 years
