What are the most common causes of purple skin?

There are several conditions that can lead to purple skin. Bruises are likely to be one of the most common. Port-wine stains are hyperpigmentation conditions that are generally non-threatening. If the area is itchy and there are bumps, a person may be suffering from lichen planus. A more serious condition that affects purple skin is Kaposi's sarcoma, a type of cancer that progresses rapidly in people with AIDS.

Bruises are one of the most common causes of purple skin. This discoloration occurs as a result of trauma. Capillaries are small blood vessels that act as exchange mechanisms between arteries and veins. When a person is injured, say for example they get punched in the arm, the capillaries can be damaged or broken to allow blood to leak and collect under the skin. Bruises are usually accompanied by pain, and people are often advised to apply cold compresses.

Port-wine stains are a type of hyperpigmentation that can result in purple skin. This condition, which often begins at birth, is caused by capillaries that don't form normally. Port-wine stains are often pink when a person is young. As a person ages, the color of the spots tends to change and become purple. Some believe that when these spots occur in the eye, there is an increased risk of glaucoma.

If the purple skin discoloration is accompanied by an itchy rash, the problem may be lichen planus. Scratching is commonly seen as the effect of making more purple bumps appear. This is a disease whose cause is unknown, but certain medications and chemicals are suspected triggers. The condition can remain active for up to a year. Although lichen planus often goes away without treatment, for many people the problem is a recurring one.

Purple skin discoloration that appears striated can be caused by spider veins. This condition is similar to varicose veins in many ways, including the fact that it is caused by poor circulation and tends to have a comparable cobweb-like appearance. However, one important difference is that the veins associated with this condition are small. Its position near the surface of the skin is the cause of the purple appearance.

Kaposi's sarcoma is a disease in which cancer cells can, among other things, cause purple skin lesions. The discoloration of these lesions is created by the blood supply flowing into them. The lesions can appear on various areas of the body, including the arms, thighs, and face. In some cases, these lesions may be swollen and painful, but some people do not experience any pain. It is widely reported that AIDS causes this type of cancer to progress much faster than normal.
