Excessive consumption of elemental silver, silver dust or silver compounds can cause the skin to be colored blue or bluish-grey. This condition is called argyria. A similar skin color can result from prolonged exposure to gold, typically as a little-used medical treatment. The gold-induced greyish skin color is called chrysiasis. Argyria and ...
Both of these conditions cause cyanosis, or a bluish discoloration of skin or mucous membranes. [4] Normally, oxygenated blood appears red and deoxygenated blood has more of a blue appearance. [5] In babies with low levels of oxygen or mixing of oxygenated and deoxygenated blood, the blood can have a blue or purple color, causing cyanosis. [6]

Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or silver dust. [1] The most dramatic symptom of argyria is that the skin turns blue or blue-gray, and is usually most prominent in sun-exposed areas of the skin.
Blue skin may refer to: Argyria, a condition caused by the ingestion of elemental silver, silver dust or silver compounds; Methemoglobinemia, the presence of excessive levels of methemoglobin in the blood; Cyanosis, a change of skin color due to decreased amounts of oxygenated hemoglobin Blue baby syndrome, cyanosis in babies
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.
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]
Schamberg's disease is caused by leaky blood vessels near the surface of the skin, capillaries, which allow red blood cells to slip through into the skin. [3] The red blood cells in the skin then fall apart and release their iron, which is released from hemoglobin. [3] The iron causes a rust color and this accounts for the orange tint of the ...
