CLINICAL PROTOCOL
Cellulitis
INTRODUCTION: Cellulitis presents as a spreading, diffuse area of skin erythema. There
may/may not be lymphadenopathy, lymphangitis, fever and systemic toxicity. Erysipelas
characteristically presents as lesions raised above the surround skin with clear lines of
demarcation. Cellulitis extends more deeply than erysipelas and will often involve
subcutaneous tissue. Predisposing factors for cellulitis include tinea of the feet, fissured
dermatitis, lymphoedema, lymphatic malformation, previous deep vein thrombosis, vascular
surgery and radiotherapy. Cellulitis may also complicate wounds (e.g. cuts, abrasions),
insect bites or scabies.
EPIDEMIOLOGY: Erysipelas is almost always caused by Streptococcus pyogenes.
Spontaneous and rapidly spreading cellulitis is often caused by Streptococcus pyogenes, or
other streptococci (grp B, C, G). Cellulitis associated with ulceration of penetrating trauma is
often caused by Staphylococcus aureus.
DIFFERENTIAL DIAGNOSIS
•
Acute contact dermatitis, septic bursitis, gout, and acute lipodermatosclerosis, which
commonly occurs in obese women with venous insufficiency. Bilateral cellulitis is very
uncommon.

history

examination
MIST: Mechanism, injuries sustained, signs vital, treatment given as first aid.
• Time of injury, onset of infection, risk factors
• Beware: Cellulitis following animal bites and
clenched fist injuries.
- Diabetic foot infection complicated by cellulitis
- Cellulitis after significant fresh or salt water
exposure.
- Cellulitis in immunosuppressed patients.
• Consider differential diagnosis:
- Deep venous thrombosis (DVT)
- Dermatosis: venous eczema, fixed drug
eruption.
- Gout
- Ruptured Baker's cyst
- Bony fracture or osteomyelitis
• Allergies / Immunisation status (e.g., tetanus)
• Prophylaxis (e.g., post-exposure rabies/bat
lyssa virus vaccination and/or immunoglobulin)
• Relevant past medical history / medication use
• Last food/fluids
Assess site and extent of infection.
Beware:
• Facial, peri orbital and upper limb
cellulitis.
• Soiled wounds with severe tissue
damage and/or devitalised tissues.
• Cellulitis on the hands, feet, and with
underlying structures involved - bone,
joint, or tendons.
• Circumferential limb involvement.
• Presence of blisters, bullae or open
wounds.
• Bilateral cellulitis – usually NOT
cellulitis.
• Be alert for necrotising fasciitis or
myonecrosis: severe constant pain,
rapid spread of infection and/or
bullae, skin necrosis, wood-hard
feeling of soft tissue, oedema beyond
erythema margin, cutaneous
