Vascular, Lymphatic and Systemic Conditions

Livedo reticularis is a lacy, purple skin discoloration that may be associated with a variety of conditions that cause circulatory abnormalities. In some people, it occurs as a normal response to cold conditions. In other cases, underlying autoimmune diseases may be responsible for livedo reticularis. Systemic lupus erythematosus or the presence of phospholipid antibodies are two conditions that may be associated with livedo reticularis. Phospholipid antibodies may predispose individuals to strokes because the blood clots more readily.
