A rare case of primary plasmacellular leukemia
The article describes the case of the primary plasmacellular leukemia as a rare case of multiple myeloma. Attention was given to an aggressive fast progressing disease course with a lethal outcome. The features of a bone marrow blood formation was a plasmablastic infiltration with a blood formation failure. A posthumous research showed a significant diffuse focal infiltration of liver, kidney and other organs with plasmablasts. The development of an acute kidney failure was caused by the kidney leukemic infiltration with primitive plasma cells. There was the hemorrhagic pneumonia typical for acute leukemia. Diversified lytic bone lesions combined with the absence of hyperproteinemia and paraproteins peculiar for chronic forms of multiple myeloma.
