According to the most accepted criteria, the leukaemic cell population is CD19\/CD5\/CD23 triple positive in CLL but CD23\u2010negative in MCL. Recently, several groups have reported CD23\u2010positive MCL cases; however, these studies mostly analysed only CD23 positivity but not intensity. To determine the role and the cut\u2010off levels of CD23 positivity and intensity in the differential diagnosis of CLL and MCL, 26 cases of MCL and 84 cases of CLL were compared using flow cytometric analysis. Our results suggest that high values of CD23 positivity (&gt;92.5%) and\/or high fluorescence intensity (&gt;44.5 mean fluorescence intensity (MFI)) of CD23 are related to CLL, whereas low CD23 positivity (&lt;30%) is related to MCL. However, cases with intermediate CD23 positivity (between 30 and 92.5%) and lower intensity (&lt;44.5 MFI) can either belong to CLL or MCL. In these cases, additional tests such as FISH analysis of the translocation t(11;14) or immunohistochemical detection of cyclin D1 overexpression are required to differentiate CLL from MCL.
