  • Acroasphyxia

  • Discoloration of the acra (blue-white) due to reduced blood supply (cyanosis).

  • Cyanotic (oxygen-poor) blood remains in the venous capillary legs and venules. Arterioles are constricted. This leads to a lack of oxygen. Reasons for this include:


  • Idiopathic
  • Genetic disposition
  • Vegetative dysregulation of microcirculation
  • Nerve-related disorders


  • Association: Livedo reticularis.

  • Whitish bluish skin discoloration. Numbness is described.

  • Medical history
  • Clinic

  • Above all, the acra are affected.

  • Frostbite
  • Verrucae vulgaris
  • Pernions
  • Mycotic infections

  • This often leads to a suspension of symptoms in middle age.
