The many faces of scleroderma.
This review integrates the clinical aspects of systemic sclerosis (SSc; scleroderma) and scleroderma-like conditions with new knowledge of the control of blood vessel tone and the role of anoxia in the activation of connective tissues leading to fibrosis. Serologic tests, high resolution computed tomographic scanning, bronchoalveolar lavage, and physiologic assessment of pulmonary gas diffusion are compared as diagnostic tools and as means of quantitating internal organ involvement. Treatment of Raynaud's disease and phenomenon, management of scleroderma renal crisis, and new means for improving gastrointestinal function with octreotide, the somatostatin analogue, also are discussed. The relationship between idiopathic forms of SSc and eosinophilic fasciitis/eosinophilia-myalgia syndrome caused by L-tryptophan ingestion and the scleroderma-like disease associated with silicone breast implants also is discussed.
