Livedoid vasculitis

Livedoid vasculitis (also known as "livedo vasculitis", livedo reticularis, and "livedoid vasculopathy") is a vascular disorder mostly affecting women. Typically, it involves a lace-like purplish discoloration of the lower extremities. The condition may be normal or may be related to more severe underlying pathology. It may be aggravated by exposure to cold and occurs most often in the lower extremities. It can also be associated with the presence of anti-cardiolipin antibodies (the Antiphospholipid syndrome).

The condition's name derives from the Latin livere meaning bluish.

Etiology

A number of conditions may cause the appearance of livedo reticularis:

Treatment

Other than identifying and treating any underlying conditions in secondary livedo, idiopathic livedo reticularis itself may improve with warming the legs, but once established the skin discolouration may become permanent.
