Shulman's syndrome includes fasciitis of rapid onset, sclerodermoid skin changes, absence of Raynaud's phenomenon, absence of visceral manifestations of progressive systemic sclerosis, hypergammaglobulinemia, transient eosinophilia, and a dramatic response to systemic corticosteroid therapy. Although this syndrome may be a variant of scleroderma, its dramatic responsiveness to corticosteroid therapy is a particularly distinguishing feature.
