[A woman with skin lesions and brain infarcts].

We present the case of a 58-year-old woman with multiple brain infarcts and livedo racemosa, a distinctive branched and irregular skin discoloration, on the trunk and limbs. Skin biopsy showed intimal proliferation with occlusion of a subcutaneous arteriole. We diagnosed Sneddon's syndrome, a rare neurocutaneous disorder likely caused by a noninflammatoryvasculopathy.
