[Raynaud's phenomenon : Practical management for dermatologists]

Abstract

Raynaud's phenomenon (RP) is a painful vasospasm of small arteries, localised in fingers and toes. Typically these body parts turn white (ischemia), then blue (deoxygenation) and then red (reperfusion). Two different types of RP exist: the common primary RP without underlying disease and the rare secondary RP, mostly associated with rheumatoid diseases such as systemic sclerosis. Thus, the dermatologist has to be aware of this condition. In this article the clinical criteria, differential diagnoses, diagnostic considerations and treatment options are discussed.
