Symptoms of pustular [PUHS-choo-lar] psoriasis include pustules (white, pus-filled, painful bumps) that may be surrounded by inflamed or reddened/discolored skin. The pus in pustules is caused by inflammation and is not contagious. Those with pustular psoriasis generally go in a cycle of the reddening/discoloring of the skin, followed by pustules and scaling.
There are different types of pustular psoriasis that depend on where the symptoms appear:
- General pustular psoriasis (GPP) or von Zumbusch [vahn zuhm-BOOSH] psoriasis describes symptoms that affect large areas of the body. This type can develop suddenly and progress quickly and often comes with a fever, chills, severe itching, change in heart rate, fatigue and muscle weakness. See a health care provider immediately if you think you may have generalized pustular psoriasis.
- Localized pustular psoriasis or palmoplantar pustular psoriasis (PPPP) is when symptoms affect the palms of the hands and/or the soles of the feet. This type often affects the base of the thumbs and the sides of the heels.
- Acropustulosis [ak-roh-PUS-chool-loh-sis] is when symptoms affect only the tips of the fingers and/or toes. This type is very rare and may present after an injury to the skin or infection.
Several factors may trigger pustular psoriasis, including:
- Certain medicines
- Starting or stopping medicines
- Exposure to too much ultraviolet (UV) light
Topicals, phototherapy, oral treatments and biologics are all possible treatment options for pustular psoriasis. You and your health care provider will discuss the best treatment plan for you based on the severity of your symptoms and your medical history.
