Pustular Psoriasis

Also Known As:

What is Pustular Psoriasis?

Psoriasis is a chronic autoimmune skin condition. The disease is characterised by the rapid build-up of skin cells, causing inflammation and scaling on the skin’s surface.

Pustular Psoriasis is an uncommon type of Psoriasis. It causes white, pus-filled blisters and broad areas of red, inflamed skin. Pustular psoriasis is typically localized to smaller areas of the body, such as the hands, feet, fingertips, but it can also be widespread.


Doctors are unclear as to the exact underlying cause of Pustular Psoriasis. However, the two general factors are:
•   Immune System: Psoriasis is an autoimmune condition. Autoimmune conditions are the result of the body attacking itself. In the case of Pustular Psoriasis, white blood cells known as T cells mistakenly attack the skin cells. This causes the skin cell production process to go into overdrive and develop too quickly.
•   Genetics: Some people inherit genes that make them more likely to develop Pustular Psoriasis. If you have an immediate family member with the skin condition, the risk for developing Pustular Psoriasis is higher.

Pustular Psoriasis primarily affects adults. Certain drugs may trigger Pustular Psoriasis, as well as rapid withdrawal from strong topical steroids or systemic medications.


Pustular Psoriasis symptoms differ from person to person and depend on the severity of disease you have. Possible symptoms of Pustular Psoriasis include:
•   Dry skin that may crack and bleed
•   Red, inflamed skin with pus-filled blisters
•   Fever
•   Chills
•   Severe itching
•   Diarrhea

Diagnosis & Treatment

Pustular Psoriasis is diagnosed by a Doctor using a physical examination. If the symptoms are unclear, or if your doctor wants to confirm their suspected diagnosis, they may conduct a biopsy.

There is currently no known cure for Pustular Psoriasis. Treatments aim to reduce inflammation and blisters as well as slow the growth of skin cells. Psoriasis treatments fall into three main categories:
•   Topical treatments
•   Systemic medications
•   Light therapy using ultraviolet (UV) or natural light

Additional Information

There are various types of Pustular Psoriasis including:
•   Von Zumbusch Pustular Psoriasis
•   Palmoplantar Pustulosis
•   Acropustulosis

Pustular Psoriasis isn’t contagious. Touching a Psoriatic lesion on another person won’t cause you to develop the condition.
