Pustular Psoriasis

This kind of psoriasis is uncommon and mostly appears in adults. It causes pus-filled bumps (pustules) surrounded by red skin. These may look infectious, but are not.

This type may show up on one area of your body, such as the hands and feet. Sometimes it covers most of your body, which is called "generalized" pustular psoriasis. When this happens it can be very serious, so get immediate medical attention.

Generalized pustular psoriasis can cause:

  • Fever
  • Chills
  • Nausea
  • Fast heart rate
  • Muscle weakness
  • Triggers include:

  • Topical medicine (ointments you put on your skin) or systemic medicine (drugs that treat your whole body), especially steroids
  • Suddenly stopping systemic drugs or strong topical steroids that you used over a large area of your body
  • Getting too much ultraviolet (UV) light without using sunscreen
  • Pregnancy
  • Stress
  • Infection
  • Exposure to certain chemicals
