The Other Psoriasis: Strategies for Recognition and Diagnosis of Pustular Psoriasis

Pustular psoriasis, including generalized pustular psoriasis (GPP) and palmoplantar pustular psoriasis (PPP), are rare disorders, with underlying pathophysiology that is distinct from psoriasis vulgaris (PV), even if there may be overlap of the conditions in some patients. Given the rarity of the disease, clinicians have limited experience with these patients, who face life-threatening flares and significantly impaired quality of life, and may not be referring when they should. This activity will improve knowledge, skills, abilities, and confidence with regard to recognition and assessment of disease severity of these important conditions.

Learning Objectives

At the conclusion of this activity, participants should be able to:

  • Compare and contrast the different pathophysiologic mechanisms of generalized pustular psoriasis (GPP) and palmoplantar pustular psoriasis (PPP) versus psoriasis vulgaris (PV)
  • Distinguish among the clinical presentations of GPP, PPP, and PV for diagnosis
  • Formulate a plan describing the steps to urgently refer patients with GPP and PPP to a specialist
