title: Intrahepatic cholestasis with predominant pericentral deposition in systemic amyloidosis.
abstract: Liver involvement in amyloidosis is rarely associated with intrahepatic cholestasis. The cases recorded in the literature indicate that there is a tendency toward periportal deposition, leading to centrilobular cholestasis. Our case was most interesting in that the amyloid deposition was most severe in the centrilobular area. Presumably there was still sufficient compression of canaliculi at the periportal level to produce obstruction of the bile flow. This would appear to be a less common but distinct variant of systemic amyloidosis with associated obstructive jaundice.
