Primary Raynaud*s phenomenon is very common, affecting approximately 3%每5% of the general population. Although much rarer, systemic sclerosis每related Raynaud*s phenomenon can be particularly severe, progressing to digital ulceration in approximately 50% of patients. Raynaud*s phenomenon can have a major impact on quality of life. This review has a focus on the systemic sclerosis每related Raynaud*s phenomenon (which is the most researched form of Raynaud*s phenomenon and probably the most challenging to treat) and on recent advances. Epidemiology (including transition from &isolated* to systemic sclerosis每related Raynaud*s phenomenon), pathogenesis, diagnosis and assessment are discussed, followed by the treatment of both &uncomplicated* and &complicated* Raynaud*s phenomena (i.e. Raynaud*s phenomenon which has progressed to digital ulceration and/or critical ischaemia). Finally, some of the major challenges for the next 5每10ˋyears are highlighted %K Systemic sclerosis %K Raynaud*s phenomenon %K diagnosis %K assessment %K management %U https://journals.sagepub.com/doi/full/10.1177/2397198319826467
