Living with Generalized pustular psoriasis

A severe form of psoriasis with repeated episodes of red, inflamed skin and small pus-filled blisters, often with fever and tiredness.

Understanding Generalized pustular psoriasis

Generalized pustular psoriasis (GPP) is a severe form of psoriasis caused by abnormal inflammation.

People have repeated episodes in which large areas of skin become red and inflamed and form small pus-filled blisters (pustules). Fever, extreme tiredness, muscle weakness, and other signs of body-wide inflammation can come with them. Episodes come and go, and can be triggered by infection, certain medicines, menstruation, or pregnancy, though the trigger is often unknown. It is usually noticed in adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Red, inflamed patches of skin
  • Small pus-filled blisters (pustules)
  • Fever
  • Fatigue
  • Joint pain or arthritis
  • Nail changes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    National Psoriasis Foundation may keep lists of experts for this condition.
