Type 1 AIP is considered as a pancreatic manifestation of immunoglobulin G4-related disease. The etiopathogenesis of AIP, particularly type 2 AIP, is largely unknown. Both types of AIP have unique pancreatic histological features; however, the radiological and clinical features may mimic those of pancreatic cancer. The most commonly used diagnostic criteria, including the Japan Pancreas Society criteria, the Mayo Clinic HISORt (histology, imaging serology, other organ involvement, and response to therapy) criteria, and the International Association of Pancreatology's international consensus diagnostic criteria, that help to differentiate AIP from pancreatic cancer are reviewed in this article. The treatment of choice for induction of remission for AIP is steroid therapy. Relapses are more common in type 1 AIP. In selected patients, immunomodulators such as azath...Continue Reading
