A case of prominent hepatic cholestasis developing to hepatic failure in lambda-AL amyloidosis.

We report a case of lambda-AL amyloidosis which manifested prominent hepatic cholestasis. The patient was a 71-year-old Japanese male who was admitted to our hospital because of abdominal distension and jaundice. Laboratory examination revealed a marked deterioration of liver function with cholestasis. Gastric biopsy revealed amyloid deposition. Under a diagnosis of primary amyloidosis he was treated with corticosteroid and dimethylsulfoxide. However, jaundice progressed, renal function deteriorated rapidly, and he died two weeks after admission. Autopsy revealed a profound deposition of lambda-AL amyloid not only in the liver but also in the kidneys, spleen, lungs, heart and intestine.
