Generalized pustular psoriasis (GPP) is an extremely rare type of psoriasis that can present in a variety of forms. Unlike the most general and common forms of psoriasis GPP usually covers the entire body and with pus-filled blisters rather than plaques. GPP can present at any age but is rarer in young children. It can appear with or without previous psoriasis conditions or history and can reoccur in periodic episodes.
