Wells syndrome associated with chronic lymphocytic leukemia.

Eosinophilic cellulitis or Wells syndrome is an uncommon skin condition of unknown etiology that can occur alone or associated with other conditions. Typically, it presents with recurrent pruritic, erythematous and edematous plaques, but it can also show clinical polymorphism. Besides the cutaneous lesions, patients can experience systemic manifestations like fever, malaise, arthralgia and peripheral blood eosinophilia. We describe a case of this rare syndrome that presented with polymorphic cutaneous lesions associated with a serious systemic disease, which was revealed through the investigation of the cutaneous disease.
