Malignancies arising from the pancreatic and biliary ductal systems present the gastroenterologist and pathologist with diagnostic challenges. Tumors of the pancreatic and/or biliary ductal system may present as either duct strictures or mass lesions. When lesions present as strictures without associated demonstrable masses, brushing cytology may represent the only reasonable diagnostic technique aside from open...
