Eosinophilic fasciitis with atypical features.

Eosinophilic fasciitis has been reported to be a syndrome distinct from progressive systemic sclerosis, due to the absence of Raynaud's phenomenon, visceral disease, and autoantibodies as well as steroid responsiveness and an abnormal histopathologic appearance that primarily involves the lower subcutis and fascia. More recent studies, however, have noted considerable overlap in the clinical, pathologic, and laboratory features of these two entities. We report a case that further blurs the distinction between eosinophilic fasciitis and progressive systemic sclerosis.
