Leucocytoclastic and renal vasculitis in a patient with autoimmune pancreatitis: new associations.

Autoimmune pancreatitis (AIP) is an uncommon condition which comprises diffuse or discrete pancreatic enlargement and irregular pancreatic duct strictures of autoimmune origin leading to pain or obstructive jaundice associated with extra-pancreatic manifestations. It is characterized by an elevated IgG, especially IgG4, level. We illustrate the first described case of a patient with AIP in association with leucocytoclastic and renal vasculitis.
