Psoriasis as autoinflammatory disease.

This article presents a summary of the evidence for a link between autoinflammatory diseases and psoriasis. The main concepts regarding the disease state of psoriasis are discussed and these lead to a change in the perspective on the clinical and pathophysiologic nature of psoriasis as a chronic, recurrent disease with important genetically defined features, and an associated or concomitant systemic inflammatory state that involves a multifactorial cellular and molecular network, transforming the old perception of psoriasis as a localized autoimmune skin disease, to one of psoriasis as a systemic inflammatory disease with autoinflammatory features and severe associated comorbid conditions.
