Core Tip
Core tip: We report a rare case of 53-year-old male patient who suffered from IgG4-related focal type of autoimmune pancreatitis (f-AIP) accompanied with Küttner’s tumour originally suspected of being pancreatic cancer with neck metastasis. The patient responded well to corticosteroid therapy but he had undergone an unnecessary pancreatic body mass resection one year ago prior to admission. Therefore, we suggest that AIP should always be considered in case of a focal pancreatic mass.
