Idiopathic livedo reticularis
Idiopathic or primary livedo reticularis refers to a netlike pattern of reddish-blue skin discoloration. Usually the legs are affected. The condition is linked to swollen blood vessels. It may get worse when the temperature is cold.
Idiopathic means the cause is unknown.
Livedo reticularis; Primary livedo reticularis
The cause of primary or idiopathic livedo reticularis is not known, therefore specific treatment is usually not recommended. If the condition is due to exposure to cold, keeping the legs warm may help relieve the symptoms. Exercise to increase circulation may also help.
