. Livedo reticularis

Livedo retikülaris

Livedo is for reticularis. It is a vasculopathy with a blue and red-like appearance on the body, on the legs, on the legs, and the skin. Livedo begins with a spasm after a cold or emotional stimulation in the reticularist, and tissue oxygen pressure decreases. In cases of prolonged spasm, microvascular thrombosis develops.


Kutis marmoratus: It is a physiologically reversible condition that occurs in cold weather in infants and many adults.

Congenital Kutis marmorata telangiecthesis: Vascular lesions on localized or widespread permanent skin seen after birth.

Primary livedo reticularis: It is the form that is generally seen in benign adults with unknown cause. It rarely requires treatment.

Secondary livedo reticularis: It is defined as livedo developing due to a systemic disease and has many reasons.


Form of occlusion in the vessel due to vasculopathy:

  • Antiphospholipid syndrome: a reaction against phosphoritis, a type of fat in the body. Depending on this, clot formation in veins
  • Cryoglobulinemia: It is the formation of microvascular accumulation due to the cold effect of antibodies in the defense system.
  • Multiple myeloma
  • Antithrombin III deficit
  • Protein C or S deficiency
  • Deep vein occlusion
