        - BILE DUCT HAMARTOMA AND HYPERPLASIA

The immunoprofile of this tumor shows CK7, EMA, CA19/9, and CK8/18 positive.  The negative stains are RCC, PSA, CK20, CDX-2.  The vimentin stain is  non-contributory.  The immunoprofile of this tumor strongly supports biliary ductal primary neoplasm but can not be separated from a pancreatic neoplasm.
