Background The role of CD200 in the differential diagnosis of chronic lymphocytic leukemia
(CLL) and classical mantle cell lymphoma (MCL) is well established. Its role in the …

Background Multiparameter flow cytometry is a useful tool for the diagnostic evaluation of
mature B‐cell neoplasms (MBN). Recently, it has been shown that CD200 may improve the …

Objectives: To analyze CD200 expression by flow cytometry in a large series of B-cell
neoplasms in a variety of tissue types in comparison with benign B-lineage cells. Methods …

CD200, a marker currently utilized in the diagnosis of B-cell lymphoma, is uniformly positive
in chronic lymphocytic leukemia/chronic lymphocytic leukemia, and is usually absent in …

Moreau score has been used to differentiate chronic lymphocytic leukemia (CLL) from other
mature B‐cell neoplasms. However, it showed limitations in Asian patients. Therefore, we …

Introduction Immunophenotyping by flow cytometry is routinely employed in distinguishing
between chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL). Inclusion of …

Background B-Cell Lymphoproliferative Disorders (B-LPDs) are a group of heterogenous
disorders characterised by the accumulation of B-cells in peripheral blood, bone marrow …

Splenic marginal zone lymphoma is a small B-cell neoplasm whose molecular pathogenesis
is still essentially unknown and whose differentiation from other small B-cell lymphomas is …

Background Hairy cell leukemia (HCL) and hairy cell leukemia variant (HCLv) are rare
