Pustular psoriasis is a form of psoriasis that appears as small, uniform pustules (inflamed elevation of the skin filled with pus). Pustular psoriasis may be widespread (generalised) or in one area (localised).

Acute, severe, generalised pustular psoriasis is termed von Zumbusch psoriasis, which is uncommon. This form of psoriasis is associated with fever and systemic illness, and is caused by infection or sudden withdrawal of systemic or very potent topical corticosteroids. Pustules occur in acutely painful, inflamed, red skin.
