title: Liver involvement in multiple myeloma.
abstract: Clinical manifestations of liver involvement in multiple myeloma (MM) are uncommon. Rare cases of MM present as acute liver disease. We report a case of a 55-year-old woman with MM who presented with painless jaundice, mild pruritus, and abnormal liver function tests resembling acute cholestatic hepatitis without the stigmata of chronic liver disease. Initial laboratories included elevated liver function tests (aspartate aminotransferase 74 U/L and alanine aminotransferase 45 U/L) and an elevated white blood cell count of 19,600 cells/microL with 33% circulating plasma cells. Myeloma parameters demonstrated an immunoglobulin G lambda monoclonal protein with lambda light-chain Bence-Jones proteinuria. Bone marrow was hypercellular with 70% plasmacytosis. A liver biopsy revealed a diffuse portal and sinusoidal infiltration of plasma cells with lambda light-chain restriction. In this report, we review the literature of liver involvement in MM.
