Also found in: Acronyms.

monoclonal B-cell lymphocytosis

The presence of excessive numbers of B lymphocytes in the bloodstream, all derived from a single parent cell. This condition sometimes precedes chronic lymphocytic leukemia, although it is often found in patients who never develop the disease.
