Rare Disease Day – February 28
Over 300 million people worldwide live with a rare disease — that’s about 1 in 25 people.
Many know the most common form of psoriasis — plaque psoriasis or psoriasis vulgaris, which causes itchy, flaky patches. But psoriatic disease is a spectrum, with several lesser-known forms.
About 3% of people with psoriasis develop pustular psoriasis, including:
🔸Generalized pustular psoriasis (GPP) – a life-threatening condition where the skin becomes intensely red, painful, and can peel in large areas.
🔸Palmoplantar pustulosis (PPP) – painful inflammation on the hand palms and feet soles.
🔸Acrodermatitis continua of Hallopeau (ACH) – affecting fingers, toes, and nails.
Other rare, serious forms include:
🔸Erythrodermic psoriasis, characterized by fiery red skin across the body, increased heart rate, severe itching, and temperature changes.
🔸Arthritis mutilans – a severe, deforming form of psoriatic arthritis.
This Rare Disease Day, we stand with everyone living across the psoriatic disease spectrum, along with their families, friends, and caregivers.
💜 Join us in raising awareness for every form of psoriatic disease.
