Livedo Reticularis
Description
Skin condition that presents with lacy, web-like purplish appearance on the skin of the arms and legs. Most commonly presents by itself without an associated illness, but may be associated with side effects from medication, autoimmune diseases (lupus, anti-phospholipid syndrome) and vascular conditions. It has been known to be more pronounced in colder climates and affect females more than males.
Symptoms
The skin has a lacy, web-like purplish appearance. The arms and legs are most often affected and the skin changes can be brought on by exposing the skin to the cold.
Tests
A history and physical exam will be done. Physical examination is all that is usually needed to diagnosis this condition. Further tests may be done if the provider suspects it to be associated with a secondary cause. At times a skin biopsy may be done.
Treatment
Warming the skin may decrease the rash. If there is a secondary cause treatment of this disorder will be done.
