Skin manifestations of raynaud’s phenomenon

Abstract

Raynaud’s phenomenon presents clinically as cold mottled skin and most commonly involves the extremities. It results from vasoconstriction of the superficial thermoregulatory vessels as an exaggerated response to cold temperatures and/or to stress. It can occur primarily, without an associated autoimmune disease, or can relate to underlying rheumatic diseases such as scleroderma or mixed connective tissue disease.
