Cellulitis/Abscess Clinical Pathway — Emergency Department and Inpatient

Cellulitis

An infection of the skin and underlying soft tissue characterized by pain, erythema, edema and warmth.

Concern for Underlying Abscess

  • Significant induration ≥ 3 cm
  • Lesion present > 2-3 days
  • History of previous drainage
  • Often has non-uniform induration

Definite Abscess

  • Fluctuant, tender red nodule that can be associated with swelling, warmth
  • Often have pustule surrounded by a rim of erythematous swelling (not to be confused with cellulitis)

The term cellulitis should not be used to describe cutaneous inflammation associated with underlying collections of pus. It is best described as subcutaneous abscess with surrounding inflammation. This distinction is important because the treatment for cellulitis is antibiotics and the treatment for abscess is incision and drainage.
