Diagnosis
Livedo reticularis is diagnosed by its clinical appearance and history. No further test or examination confirms idiopathic livedo reticularis, however, further investigations may be undertaken where an underlying cause is suspected such as skin biopsies, or blood tests for antibodies associated with antiphospholipid syndrome or systemic lupus erythematosus. Treatment
Other than identifying and treating any underlying conditions in secondary livedo, idiopathic livedo reticularis may improve with warming the area. See also
Livedoid dermatitis
Livedo racemosa
Perinatal gangrene of the buttock
erythema ab igne (AKA livedo recticularis e calore) - a rash caused by prolonged heat exposure (e.g. hot water bottle or heat pad)
