Psoriasis (say "suh-RY-uh-sus")
is a long-term (chronic) skin problem that causes skin cells to grow too
quickly, resulting in thick, white, silvery, or red patches of skin. Normally,
skin cells grow gradually and flake off about every 4 weeks. New skin cells
grow to replace the outer layers of the skin as they shed. But in psoriasis,
new skin cells move rapidly to the surface of the skin in days rather than
weeks. They build up and form thick patches called plaques (say "plax").
The patches range in size from small to large. They most often appear on
the knees, elbows, scalp, hands, feet, or lower back. Psoriasis is most common
in adults. But children and teens can get it too.
psoriasis can be embarrassing, and many people, especially teens, avoid
swimming and other situations where patches can show. But there are many types
of treatment that can help keep psoriasis under control.
