There are two types of autoimmune pancreatitis: type 1, in which the pancreas is involved as one part of a systemic immunoglobulin G4-related disease, and type 2, generally without immunoglobulin G4-positive cells and without systemic involvement.engImmunoglobulin G4Pancreatic cancerAutoimmune pancreatitisjournal article10.1159/000461589
