Content: Underlying this transition is pallor and cyanosis of the digits, followed by a reactive hyperemia as they rewarm. When extreme and frequent, this phenomenon can lead to digital ulcerations, gangrene, or amputation. Ulceration can predispose to chronic infections of the involved site. Esophageal dysmotility
Presents as a sensation of food getting stuck ( dysphagia) in the mid- or lower esophagus, atypical chest pain, or cough. People often state they must drink liquids to swallow solid food. This motility problem results from atrophy of the gastrointestinal tract wall smooth muscle. This change may occur with or without pathologic evidence of significant tissue fibrosis. Sclerodactyly
Though it is the most easily recognizable manifestation, it is not prominent in all patients. Thickening generally only involves the skin of the fingers distal to the metacarpophalangeal joints in CREST. Early in the course of the disease, the skin may appear edematous and inflamed.
