Highlights & Basics
- Limited cutaneous systemic sclerosis is a subset of systemic sclerosis characterized by skin fibrosis of the fingers (sclerodactyly) and, in some cases, of the face and neck or the skin distal to the elbows and/or knees. It does not affect the upper arms, upper legs, or trunk.
- Previously known as CREST syndrome, which stands for the presence of calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia. This term is rarely used now as CREST features are not limited to this type of systemic sclerosis.
- Presence of anticentromere antibody implies better prognosis and longer survival.
- Treatment is targeted to symptoms, or to organs involved, and to influencing the fibrosis of the skin and other connective tissues.
- Renal crisis will be encountered by a small number of patients only; ACE inhibitors reduce the likelihood of renal failure, dialysis, and death from this complication.
