Biclonal Low-Grade B Cell Lymphoma as Detected by Multiparametric Flow Cytometry in Blood and Marrow.

ABSTRACT: Biclonal B cell lymphomas (BCL) of two different low-grade components are rare. Multiparametric flow cytometry (MFC) is an integral tool in lymphoma diagnosis and very efficient in picking up BCL cases, especially when the associated second component is small. We studied the incidence of BCL in the routine blood and marrow samples sent for immunophenotyping by MFC. A total of 376 cases were analyzed retrospectively. We studied their clinical, immunophenotypic, molecular, and cytogenetic findings with literature review. We found five cases of BCL with two different clonal low-grade B cell components at an incidence of 1.3%. All cases were males with a median age of 68 years. The chronic lymphocytic leukemia (CLL) clone was present in all 5 cases. The other associated component in cases 1 to
