A Case of Multiple Myeloma with Multiple Intrahepatic Extramedullary Plasmacytomas / 대한혈액학회지

ABSTRACT

Plasma cell neoplasms of the liver include primary extramedullary plasmacytoma and a local manifestation of multiple myeloma. Extramedullary plasmacytoma of the liver in multiple myeloma is extremely rare although extramedullary involvement frequently occur in extramedullary sites such as lymph nodes, lung, pleura, gastrointestinal tracts, nervous system and spleen. We experienced a case of multiple myeloma with multiple intrahepatic extramedullary plasmacytomas which initially presented as metastatic cancer of the liver. Intrahepatic extramedullary plasmacytoma confirmed by ultrasono-guided liver biopsy, which disclosed numerous neoplastic plasma cell infiltration.
