Psoriasis

What is psoriasis?

Psoriasis is an unpredictable chronic skin disease that roughly affects 7.5 to 8.5 million people in the U.S. Psoriasis is not a contagious disease however, it is unpredictable and flare ups could occur weekly or monthly.

It causes rapid skin cell reproduction resulting in red, dry patches of thickened skin. There is certainly no cure for psoriasis. About 80% of people with psoriasis live with plaque psoriasis, which is also known as psoriasis vulgaris.

There are five types of psoriasis:

  • Plaque Psoriasis: is the most common type of psoriasis and has patches of oval shaped red plaques
  • Guttate Psoriasis: Looks like small, salmon- pink drops on the skin

  • Pustular Psoriasis: Uncommon form of psoriasis which creates red bumps on the skin filled with pus and surrounding skin is red
  • Erythrodermic Psoriasis: Skin’s surface affected by inflammation, redness and scaling.

What causes Psoriasis?

Psoriasis is not fully understood however, there are two hypotheses for psoriasis. The first one is that excessive skin growth is due to the fault of the epidermis and keratinocyes. The second hypothesis is that T-cells migrate to the dermis and release cytokines which cause inflammation and rapid production of skin cells. Although psoriasis is not contagious, it has a large hereditary component associated with genes; however it is unclear how they work together.
