Because white blood cells continue to grow so that accumulate and assemble into plaques. A person with psoriasis generally has patches of raised red skin with thick silvery scales. Affected skin may be red and scaly or pustules, depending on the type of psoriasis the individual has. Psoriasis is caused because the immune system plays an important role. The immune system makes white blood cells that protect the body from infection. In psoriasis, T cells (a type of white blood cell) abnormally trigger inflammation in the skin. T cells also cause skin cells to grow faster than normal and pile up in raised patches on the outer surface of the skin.
Psoriasis is usually found in the arms, legs, trunk, nails, or scalp, but psoriasis can be found in every part of the skin. Areas most often affected are the knees and elbows.
