Abstract

There are two forms of autoimmune pancreatitis (AIP). Type 1 is associated with immunoglobulin G4 (IgG4)-related systemic fibro- inflammatory disease, whereas type 2 AIP is localized to the pancreas and not associated with IgG4. The number of children presenting with type 2 AIP has recently increased. Here, we report a case of type 2 AIP in a 16-year-old adolescent who presented with clinical acute pancreatitis and associated pancreatic masses. He was diagnosed with type 2 AIP based on pancreatic biopsy results showing granulocytic epithelial lesions and supportive radiological imaging and steroid responsiveness.
