Diffuse fasciitis with eosinophilia: histological and electron microscopic study

Abstract
A female case of diffuse fasciitis with eosinophilia (or eosinophilic fasciitis) is reported. This disease is characterized by suddenly developed circumscribed subcutaneous indurations on the extremities, hyalinized fibrosis of the fascia and peripheral eosinophilia. Our patient further displayed Raynaud's phenomenon preceded by thrombophlebitis, and histological and electron microscopical features of her subcutaneous hyalinized area centering at the fascia closely resembled those of morphaea.
