Pustular Psoriasis (PP)
What is Pustular Psoriasis?
Pustular psoriasis (PP) is a rare type of psoriasis that appears as an eruption of white pustules surrounded by inflammation of the skin. It’s usually characterized by red, scaly skin and pustules (small fluid-filled bumps) and can occur anywhere on the body. As with all forms of psoriasis, PP is thought to be triggered by an autoimmune response, although the exact cause is not known.
Signs & Symptoms
The most common symptoms of PP are worsening of itching and redness of the skin, white blisters on the skin and inflamed areas that may weep or ooze fluids. These symptoms can be very painful and may require treatment. PP can be localized to certain areas of the body or it may cover the entire body. It may come and go in cycles over a period of time.
Risk Factors
Most cases of PP occur in adults between the ages of 30 and 60, though it can occur in any age group. There are certain risk factors associated with an increased risk of developing PP, including:
- Family history of psoriasis
- Having an existing autoimmune disorder
- Exposure to certain medications
- Exposure to certain environmental triggers, such as sunburn or stress
Diagnosis and Treatment
A doctor will usually diagnose PP by doing a physical examination and reviewing your medical history. They may also take a sample of the affected skin to test for bacteria or fungus. Treatment for PP may involve:
- Corticosteroids – used to reduce inflammation and reduce the appearance of skin lesions.
- Phototherapy – exposure to ultraviolet light to reduce inflammation.
- Immunosuppressants – to reduce the body’s immune response.
- Biologic agents – injectable or IV treatments that can help reduce inflammation and itching.
- Topical treatments – creams and ointments applied directly to the skin to help reduce pain and itching.
PP can be a very uncomfortable condition, and it’s important to talk to your doctor about the best treatment options for your individual case.
