title: Primary Amyloidosis Presenting as Common Bile Duct Obstruction With Cholangitis.
abstract: A 61-year-old woman presented with features of acute cholangitis and distal common bile duct obstruction. Histopathology from ampulla of Vater biopsy demonstrated extensive local amyloid deposition. Amyloidomas can cause local obstructive effects and have been described in the small intestine, stomach, and gallbladder. This is the second case of a discrete amyloid deposit causing extrahepatic biliary obstruction and cholangitis.
