Eosinophilic cellulitis in a family.

Eosinophilic cellulitis (Wells' syndrome) is characterized by recurrent episodes of nonpruritic, indurative, cutaneous swellings. Three cases of this syndrome occurred in two male siblings and their mother. In all three family members, skin lesions appeared early in infancy. Unusual clinical manifestations included eosinophilic pleural effusions and pericarditis.
