There are also a number of other conditions that affect hands, feet, and parts of the face with associated skin color changes that need to be differentiated from acrocyanosis: Raynaud phenomenon, pernio, acrorygosis, erythromelalgia, and blue finger syndrome. The diagnosis may be challenging in some cases, especially when these syndromes co-exist.
Cold agglutinin-mediated acrocyanosis differs from Raynaud phenomenon. In Raynaud phenomena, caused by vasospasm, a triphasic color change occurs, from white to blue to red, based on vasculature response. No evidence of such a response exists in cold agglutinin disease.
Symptoms of AIHA may be due to the underlying anemia; including shortness of breath or dyspnea, fatigue, headache, muscle weakness and pallor. [10] In cold agglutinin disease (cold antibody type), agglutination and impaired passage of red blood cells through capillaries in the extremities causes acrocyanosis and Raynaud phenomenon with a rare complication of gangrene [4]
The temporary loss of blood supply to the extremities known as Raynaud’s syndrome is also common. It tends to be diagnosed most often in young women. It tends to be diagnosed most often in young ...
Raynaud’s phenomenon, which causes parts of the body like the fingers and the toes to go cold and numb, likely stems from two genes, a study published Thursday in the journal Nature ...
Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [ 1 ]
Cyanosis is the change of body tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. [1]
Related medical conditions include Raynaud syndrome, erythromelalgia, frostbite, and trench foot, as well as connective tissue diseases such as lupus or vasculitis. In infants affected by Aicardi–Goutières syndrome (a rare inherited condition which affects the nervous system ) chilblain-like symptoms occur together with severe neurologic ...
