In multiple myeloma, malignant cells are derived from which lineage?

Explanation:
Malignant cells in this disease are mature plasma cells, the antibody-secreting end stage of the B lymphocyte lineage. Plasma cells originate from B cells that have been activated and differentiated; in multiple myeloma, a single clone of these plasma cells expands in the bone marrow and produces a monoclonal immunoglobulin. T lymphocytes and monocytes come from different lineages and do not become plasma cells, so they are not the source of the malignant cells in this condition.
