Eosinophilic cellulitis, also known as Wells' syndrome (not to be confused with Weil's disease), is a skin disease that presents with painful, red, raised, and warm patches of skin.[2] The rash comes on suddenly, lasts for a few weeks, and often repeatedly comes back.[2] Scar formation does not typically occur.[1]
Eosinophilic cellulitis is of unknown cause.[2] It is suspected to be an autoimmune disorder.[2] It may be triggered by bites from insects and arachnids such as spiders, fleas, or ticks, or from medications or surgery.[2] Diagnosis is made after other potential cases are ruled out.[1] Skin biopsy of the affected areas may show an increased number of eosinophils.[2] Other conditions that may appear similar include cellulitis, contact dermatitis, and severe allergic reactions such as anaphylaxis.[2]
Treatment is often with a corticosteroids.[2] Steroids applied as a cream is generally recommended over the use of steroids by mouth.[3] Antihistamines may be used to help with itchiness.[1] Many times the condition goes away after a few weeks without treatment.[2] The condition is uncommon.[1] It affects both sexes with the same frequency.[2] It was first described by George Crichton Wells in 1971.[1][4]
Cause
Eosinophilic cellulitis is of unknown cause.[2] It is suspected to be an autoimmune disorder.[2] It may be triggered by bites from insects such as mosquitos,[5] spiders, fleas, or ticks, or from medications or surgery.[2]
Diagnosis
Diagnosis requires ruling out other potential causes.[1] This includes ruling out vasculitis on skin biopsy.[1]
Treatment
Treatment is often with a steroids.[2] This can be either applied as a cream or taken by mouth.[3] As the condition tends to get better on its own taking steroids by mouth should generally only be tried if the rash covers a large area and it does not get better with other measures.[3]
