Livedo reticularis is a common skin finding consisting of a mottled reticulated vascular pattern that appears as a lace-like purplish discoloration of the skin. [1] The discoloration is caused by reduction in blood flow through the arterioles that supply the cutaneous capillaries, resulting in deoxygenated blood showing as blue discoloration ().
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] Cyanosis is apparent usually in the body tissues covered with thin skin , including the mucous membranes , lips, nail beds , and ear lobes. [ 1 ]
Essentially, the main symptoms making this disease dangerous are a result of a lack of oxygen reaching vital tissues, muscles, and organs. Cyanosis is typically classified as having 85% or less oxygen saturation in your bloodstream. [15] Typically your blood oxygen saturation levels should fall around 95% or higher. [15]
Acrocyanosis may be a sign of a more serious medical problem, such as connective tissue diseases and diseases associated with central cyanosis. Other causative conditions include infections, toxicities, antiphospholipid syndrome, cryoglobulinemia, neoplasms. In these cases, the observed cutaneous changes are known as "secondary acrocyanosis".
Sickle cell disease is a group of inherited blood disorders, caused by a genetic abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [57] Under certain circumstances, this leads to the red blood cells adopting an abnormal sickle -like shape; with this shape, they are unable to deform as they pass through capillaries ...

Cyanotic heart disease, which is a category of congenital heart defect that results in low levels of oxygen in the blood. [2] This can be caused by either reduced blood flow to the lungs or mixing of oxygenated and deoxygenated blood. [2] Methemoglobinemia, which is a disease defined by high levels of methemoglobin in the blood.
