Pustular psoriasis is a rare form of psoriasis that causes pustules, or pus-filled blisters, to form on the skin.

These pustules can be highly uncomfortable and make it difficult to carry out daily activities.

There are several types of pustular psoriasis, including generalized pustular psoriasis, which affects the entire body, and localized pustular psoriasis, which affects specific body areas. Generalized pustular psoriasis can be particularly severe and can cause fever, chills, and other systemic symptoms. Symptoms of pustular psoriasis include red, inflamed skin covered in pus-filled blisters. The affected areas may be itchy, painful, and tender to the touch. In severe cases, the blisters can break open and cause bleeding and oozing.

The exact cause of pustular psoriasis is unknown, but it is believed to be an autoimmune disorder in which the immune system mistakenly attacks healthy skin cells. Specific triggers, such as stress, infection, or injury to the skin, can also exacerbate symptoms of pustular psoriasis.
