Lambda light chain myeloma presenting as nodular hepatic lesion: a clinical rarity

We report a case of a 63-year-old lady presenting with pain in the right hypochondrium, jaundice, anorexia, and firm tender hepatomegaly with remarkably high serum alkaline phosphatase. Abdominal ultrasonography revealed a hypoechoic solid space-occupying lesion in right lobe of liver which was cytologically diagnosed as hepatic plasmacytoma. Serum and urine immunofixation electrophoresis, serum free light chain ratio, and bone marrow examination further confirmed the presence of lambda light chain multiple myeloma in the background. The patient achieved complete remission after four cycles of induction therapy with thalidomide and dexamethasone protocol and consolidated with further four cycles of the same regimen.
