title: Severe acute cholestatic hepatitis by infiltration of monoclonal plasma cells in multiple myeloma.
abstract: BACKGROUND
  Plasma cell infiltration of the liver can be detected in 25 to 40% of patients with multiple myeloma. However, there are only rare cases of multiple myeloma clinically presenting as acute liver disease.
  
  
  METHODS
  We report an 88-year-old woman with painless jaundice and abnormal liver function tests, resembling acute cholestatic hepatitis. Viral hepatitis as well as autoimmune hepatitis could be excluded. Liver biopsy revealed a diffuse portal and sinusoidal infiltration of plasma cells with lambda light chain restriction. Serological immune fixation disclosed monoclonal gammopathy of IgG lambda with bone marrow infiltration of 25% plasma cells. After administration of 60 mg prednisolone per day, the elevated liver enzymes declined considerably.
  
  
  CONCLUSIONS
  Hepatic plasma cell infiltration of multiple myeloma can, in rare cases, manifest as acute cholestatic hepatitis, which may respond to treatment with corticosteroids.
