Heterogeneous group of vascular syndromes characterized by the morphological phenomenon " Livedo" as reticular (retiform), cold-driven visible vascular accentuation of the deep cutaneous vascular plexus.
ClassificationThis section has been translated automatically.
Livedo reticularis: Due to physical noxae that lead to functional disturbances of the blood circulation:
- Cutis marmorata (after exposure to cold)
- Erythema e calore (after heat exposure)
- For central disorders of innervation (apoplexy, trauma)
- In case of maturation disorders of the subcutaneous fatty tissue:
- Other:
- Impediment of influence (arterial):
- Arteriosclerosis:
- Calciphylaxis, cutaneous
- Oxalosis
- vasculitis:
- Polyangiitis microscopic (cutaneous)
- Lupus erythematosus, systemic
- Antiphospholipid Syndrome
- endangiitis obliterans
- Livedovasculopathy
- Embolia cutis medicamentosa (also in toxicomania)
- Sneddon syndrome
- Septic embolisms (see below sepsis, skin changes).
- obstruction of the outflow (venous):
- Vasculitis, necrotizing
- Livedovasculopathy (due to thrombosis of superficial veins)
- Increase in viscosity:
- Cryoglobulinemia
- Cryofibrinogenesis
- Thrombocytosis
- Polyglobulia
- polycythemia vera
- Myeloma, multiple
- Hypercoagulatory states (protein C/S and antithrombin III deficiency)
- Intravascular coagulation or agglutination (see below thrombocytopenia, heparin-induced; see below coumarin necrosis).
