Livedo reticularis: A mottled purplish discoloration of the skin. Livedo reticularis can be a normal condition that is simply more obvious when a person is exposed to the cold. It can also be an indicator of impaired circulation. Livedo reticularis has been reported in association with autoimmune diseases, such as systemic lupus erythematosus; abnormal antibodies referred to as phospholipid antibodies; and a syndrome featuring phospholipid antibodies with multiple brain strokes.
