Definition: Acrocyanosis is a skin condition that causes pink, red or purple patches on the skin. It is caused by changes in blood pigment levels (like haemoglobin), which can occur due to stress, infections or even some medications. A 'haemoglobin' refers to oxygenated hemoglobin in the blood. In this condition of acrocyanosis, haemoglobin has been reduced in the lungs and spleen, causing a decrease in oxygen-carrying capacity. This is caused by anemia (anemia) where there is too little red blood cells or the number of red blood cells decreases. The cause of haemoglobin reduction in the lungs and spleen can be due to stress, infections, certain medications, or even genetic factors. In some cases, it can also be caused by a serious illness such as chronic fatigue syndrome (CFS) or autoimmune disorders. The symptoms vary from person to person, but typically include redness, itching, pain, swelling, warmth and bruising in the affected areas. Acrocyanosis is a common condition and affects millions of people worldwide. It can affect any part of the body including the skin, eyes, lips, nails or mucous membranes, as well as the organs like the heart, lungs, bones and brain. Symptoms often start as small patches on the skin and spread to other parts of the body.
