Dear Fellow Flow Users, I am interested in comments on this new case of Acute Leukaemia. A 53 year old male presented with WCC-4.64 x 10^9/L, Hb-95 g/L, Platelets-148 x 10^9/L and Blasts-1.21 x 10^9/L. Bone Marrow flow cytometry results on the abnormal cells (78%) using CD45/LogSS gating are for surface markers CD2, CD10, CD11b, CD13, CD14, CD19, CD20, CD33, CD56 and CD61 <1%, CD15 -14% weak, CD34 - 98%, CD38 - 99%, CD71 - 39% weak and HLADR - 95%. For cytoplasmic markers CD3 and CD20 <1%, CD79a - 21% weak, MPO - 20% weak and TdT - 89%. There was no co-expression between CD79a and MPO. In summary the patient is positive for surface CD34, CD38, HLADR, cytoplasmic TdT and weakly positive for cytoplasmic CD79a and MPO. I am looking forward to your comments. Regards Lynette
