Mycophenolate mofetil for maintenance of remission in steroid-dependent autoimmune pancreatitis

Figure 1 Cholangiogram obtained during endoscopic retrograde cholangiopancreatography demonstrating a marked 18 mm stricture in the distal common bile duct with diffuse irregular stricturing of the intrahepatic ducts bilaterally.

Figure 2 Histopathologic images demonstrating the findings from the patient’s ampullary biopsy. A: A hematoxylin eosin stained biopsy at 20 x magnification revealed chronic active inflammation; B: An IgG4 stain revealed approximately 20-25 IgG4-containing plasma cells/high power field, consistent with autoimmune pancreatitis.
