[Livedo reticular: classification, causes and differential diagnoses].
Livedo reticularis (LR) is a common finding and results         from a physiological vasospastic response to cold or         systemic disease, characterized by a pattern of cyanotic         discoloration, or erythematous-cyanotic aspect. LR         can be congenital or acquired. Among the acquired LR         stand out from the physiological or cutis marmorata,         the idiopathic, the induced vasospastic, those due to         intravascular diseases or even in the wall of the vessels.         This article reviews several clinical features, differential         diagnosis and various causes of livedo.
