Its diagnosis is also a clinical challenge. This form of chronic pancreatitis often presents itself with obstructive jaundice and/or a pancreatic mass and it is sometimes misdiagnosed as pancreatic cancer. We describe the case of a 13-year-old boy with obstructive jaundice and a 4 cm mass in the head of the pancreas that was diagnosed as AIP with associated ulcerative colitis.engAdolescentAutoimmune Diseases / immunology*Colitis, Ulcerative / immunology*Jaundice, Obstructive / immunology*Pancreatitis / immunology*HDE GAS PEDjournal article10.1136/bcr-2018-227888
