Wells syndrome is a rare eosinophilic disorder that primarily affects the skin. Affected people typically develop a skin rash that is often preceded by itching or burning skin. The rash consists of raised, red, swollen areas that may be warm to the touch. The symptoms generally come on rapidly and may last four to eight weeks. In some cases, the rash may recur (occur frequently or repeatedly) for years. The exact underlying cause of Wells syndrome is currently unknown; however, some scientists believe that it may be an autoimmune reaction. Oral or topical corticosteroids are commonly used to treat Wells syndrome, although antifungal drugs, antibiotics, immunosuppressants, and/or antihistamines have also been used with varying degrees of success.
