Psoriasis

Robert Sarro, M.D. and the healthcare professionals at Premier Dermatology Partners believe that well-informed patients are better equipped to make decisions regarding their health.  Therefore, we have created an extensive patient library covering an array of dermatological topics. 

As always, you can contact a member of our staff to answer any questions or concerns.

Psoriasis: Overview

What is psoriasis?

Psoriasis (sore-EYE-ah-sis) is a chronic (long-lasting) disease. It develops when a person’s immune system sends faulty signals that tell skin cells to grow too quickly. New skin cells form in days rather than weeks.

The body does not shed these excess skin cells. The skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.
Psoriasis may look contagious, but it's not.

You cannot get psoriasis from touching someone who has it. To get psoriasis, a person must inherit the genes that cause it.

Types of psoriasis

If you have psoriasis, you will have one or more of these types:

  • Plaque (also called psoriasis vulgaris).
  • Guttate.
  • Inverse (also called flexural psoriasis or intertriginous psoriasis).
  • Pustular.
  • Erythrodermic (also called exfoliative psoriasis).

Some people get more than one type. Sometimes a person gets one type of psoriasis, and then the type of psoriasis changes.
