Picture of Pustular Psoriasis

Pustular psoriasis is an uncommon form of psoriasis. People with pustular psoriasis have clearly defined, raised bumps on the skin that are filled with pus (pustules). The skin under and around these bumps is reddish. Pustular psoriasis may cause large portions of your skin to redden. The skin changes that occur before, during, or after an episode of pustular psoriasis can be similar to those of regular psoriasis.
