title: [Observation of a case of Wells syndrome: ultrastructural study].
abstract: A new case of Wells' syndrome is reported. Histologically the infiltrate of eosinophils extended to the deep dermis and the subcutaneous fat. The characteristic flame figures are seen in the dermis. Ultrastructurally eosinophils were numerous half of then degranulated. No injury to the vessel walls and collagen bundles were observed. The Authors emphasized that Wells' syndrome is a distinctive entity clinical, on likely autoimmune basis, with multiple triggering factors and peculiar histopathologic but not diagnostic picture.
