    Psoriasis and Crohn’s disease are chronic immune-mediated inflammatory diseases with partial immune convergence, influenced by tissue context.

  • 2

    TNF-α and IL-23-centered type 17 immunity are significant shared pathways between psoriasis and Crohn’s disease.

  • 3

    Epidemiological studies indicate a bidirectional association, with Crohn’s disease more prevalent in patients with severe psoriasis.

  • 4

    Genetic evidence shows shared susceptibility signals between psoriasis and inflammatory bowel disease, particularly in immune-regulatory pathways.

  • 5

    Therapeutic options include TNF inhibitors and IL-12/23 blockade, but organ-specific responses complicate treatment strategies.
