Unusual Presentation of Wells Syndrome: A Case Report

Wells syndrome is an uncommon disease that typically presents as edematous erythematous plaques, usually preceded by burning or itching of the skin. Histopathological examination shows dense dermal eosinophilic infiltrates in an edematous dermis at the acute phase of lesions. Some of the identified triggering factors include infection, arthropod bites, hematological malignancies, thimerosal containing vaccines and drugs such as penicillin, lincomycin, tetracycline, minocycline and ampicillin. Here we describe a case of Wells syndrome in a 75-year-old woman that its outstanding feature was its large size. Although this case was resistant to our treatment, the condition improved spontaneously after several weeks without administering any other alternative treatments. On the other hand, despite its large size, this case had no identifiable trigger.
