Description | A rare non-inflammatory thrombotic vasculopathy predominantly affecting women in young adulthood. Livedo racemosa is a persistent net-like violaceous-cyanotic, mottled discolouration of the skin that is exacerbated by cold or pregnancy. Neurological manifestations include recurrent transient ischaemic attacks and infarcts. While about 50% of cases are idiopathic, the disease can be associated with autoimmune diseases like systemic lupus erythematosus and antiphospholipid syndrome. Genetic factors may play a role in the pathogenesis. Loss-of-function mutations in cat eye syndrome chromosome region candidate 1 CECR1 (22q11.2) encoding adenosine deaminase 2 have been found. Most cases are sporadic but some familial cases with an autosomal dominant inheritance have been reported. |
