Livedo reticularis can be a normal condition that is simply more obvious when a person is exposed to the cold.

Livedo reticularis 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. Examples of these antibodies are the cardiolipin antibody and falsely positive testing for syphilis. A syndrome featuring phospholipid antibodies with multiple brain strokes. It is felt that the blood of these patients has a propensity to clot which may predispose to stroke.
