ABSTRACT
The differentiation of mass-forming autoimmune pancreatitis (AIP) from pancreatic cancer is critical because AIP can be successfully treated with steroid therapy and unnecessary surgery avoided. We herein report a case of 69-year-old male with a prior history of recurrent AIP who developed a pancreatic body mass with upstream duct dilatation. Laboratory findings were nonspecific for AIP or pancreatic cancer, although an endoscopic ultrasonography-guided biopsy revealed chronic inflammation. To differentiate mass-forming AIP from pancreatic cancer, we administered oral steroids for 2 weeks. After steroid therapy, a computed tomography scan revealed a decrease in the pancreatic mass size and improvement in dilatation of the upstream duct. So we could differentiate mass-forming AIP from pancreatic cancer; thereafter resolution of pancreatic lesion could be achieved with further steroid therapy. In conclusion, a 2-week steroid trial followed by radiologic imaging was helpful to differentiate mass-forming AIP from pancreatic cancer.
