We analyzed the peripheral blood and BM samples of 131 patients with B-cell CLDs (including 91 CLL, 15 atypical CLL, 14 MCL, and 11 CD5-/CD10-lymphoma patients) from April 2018 to April 2019, using a panel of specific markers by flow cytometry. Here, MME is linked to B-cell chronic lymphocytic leukemia.
