CREST syndrome is a particular form of a condition called scleroderma. CREST actually stands for the cardinal signs and symptoms associated with the condition: * Calcinosis (calcium deposits in the hands, particularly) * Raynaud's phenomenon * Esophageal dysmotility (difficulty/pain swallowing) * Sclerodactly (tightness of skin around the fingers and hands) * Telangiectasias (also called spider veins) A very nice write up of the condition is available from eMedicine; see the related links section of this answer.
