What is Psoriasis in Children?

Psoriasis is an inflammatory skin disorder. Normal skin cells develop and shed every 28 to 30 days. In children with psoriasis, the skin cells in the areas that are affected develop every 3-4 days. The raised, scaly-looking lesions are actually a buildup of skin and the redness is caused by extra blood accumulating in this area. Although the cause of psoriasis is not known, some research suggests that it is triggered by the immune system.

In children, there are two forms of psoriasis:

  • Plaque psoriasis.  This condition is often seen in toddlers as a raised, red skin lesion that is covered with a silvery white scale.  It is most commonly found on the elbows, knees, scalp and lower back.
  • Guttate psoriasis.  A type of psoriasis that appears as small, red dot-like lesions usually on the trunk or limbs.
