Myeloma and severe cholestasis.

Amyloidosis is a frequent complication of multiple myeloma. Liver involvement is common in amyloidosis. Hepatic dysfunction and liver chemistry abnormalities are often mild or absent and obstructive jaundice is rare. We report on a 44-year-old patient with multiple myeloma and rapidly deteriorating liver involvement with severe intrahepatic cholestasis. Autopsy showed widespread amyloidosis primarily involving the liver. This unusual cholestatic manifestation of hepatic amyloidosis has an uniformly poor prognosis, with death occurring within a few months. We discuss the clinical and pathologic aspects.
