Ample evidence was provided these past decades that leukaemic stem cells (LSC) play a role in the outcome of adult and paediatric acute myeloid leukaemia (AML) patients. Although it is generally accepted that the CD34+/ CD38- compartment is most LSC-enriched, novel data have emerged illustrating a distinct biology between CD34+ and CD34- AML. In this review, we discuss the main LSC phenotypes in CD34+ and CD34- AML , as they are of utmost importance for the development of broadly applicable LSC-targeted strategies. The leukaemia-initiating capacity of these cells upon xenografting is still considered to be the gold standard for LSC detection. However, more feasible techniques have been researched to allow the implementation of LSC measurements into clinical practice. Here, we summarise the current state-of-the-art methodologies using flow cytometry and molecular detection, and emphasise their relevance in terms of prognosis and targeted drug therapy.

In November 2019, the Belgian Society for the Advancement of Cytometry (BSAC) and the Dutch Society for Cytometry (NVC) jointly organised a two-day international congress on developments in (flow) cytometry. With over 150 participants, the congress was well attended and received. Here we briefly discuss the most important highlights from this congress.

We report a rare case of biclonal biphenotypic B-cell lymphocytosis with chronic lymphocytic leukaemia phenotype. Clonality was initially misjudged by immunophenotyping because of its polyphenotypic pattern. Polymerase chain reaction analysis revealed clonality of the immunoglobulin heavy chain and kappa light chain gene rearrangement, indicating the presence of a monoclonal B-lymphocyte population. Immunophenotyping was repeated after cell sorting and revealed two CD5+CD19+ populations with different light chain restriction. Different genetic abnormalities for both clones, as evidenced by fluorescence in situ hybridisation and hypermutation analysis, support the diagnosis of two independently originated but co-existing B-cell clones. This case illustrates the importance of using multiple techniques in the diagnostic work-up of haematological malignancies.
