Vascular acrosyndromes

Vascular acrosyndromes are defined here as a group of syndromes of the extremities (limbs, nose, ears, external genitalia) manifested by disturbances of color, temperature and/or pain, and resulting from vasomotor disorders. They are very common (overall prevalence 20%, dominated by Raynaud's phenomenon) and their prognosis, although generally favorable, depends on any underlying pathology.

Vascular acrosyndromes, dealt with in dedicated chapters, include:

• Acrocyanosis
• Raynaud phenomenon
• Chilblains
• Erythermalgia

Depending on the case, differential diagnosis may be required with other acrosyndromes (complex regional pain syndrome, ductal syndromes, atheromatous arteriopathies, cholesterol or septic embolisms, etc.).
