Gastric Involvement in Autoimmune Pancreatitis / 대한소화기내시경학회지

ABSTRACT

Autoimmune pancreatitis is now considered to be a systemic fibroinflammatory disease that can involve multiple organs. As it is associated with IgG4-positive plasma cells by an autoimmune mechanism, extrapancreatic organs as well as the pancreas could be affected with a lymphoplasmacytic infiltrate. The proximal bile duct, the salivary gland, the retroperitoneum and the kidney are well known to be involved with, but less is known about the involvement of hollow viscus which is pathologically associated with autoimmune pancreatitis. We report here on a case of gastric involvement in a 53-year-old man with autoimmune pancreatitis.
