Sneddon disease

General: Livedo reticularis; neurologic abnormalities; 313b17d labile hypertension; apparently autosomal dominant inheritance characterized by a rare potentially severe, arterioocclusive disorder; probably an immunologically mediated disorder leading to the migration and proliferation of smooth cells of small arteries, resulting in partial or complete narrowing of the vessel lumen.

Ocular: Central retinal artery occlusion; visual loss; optic atrophy; visual field defect; cherry-red macula.

Clinical: Diffuse headaches; hemihypesthesia; transient aphasic attack; hemianopsia; reticular blue discoloration of skin; hypertension; transient global amnesia; livedo reticularis; progressive neurologic deterioration; multiple ischemic cerebrovascular episodes; renal cell carcinoma.
