PG - 77-80 AB - Cytogenetically-unrelated clones are infrequently seen in hematologic malignancies, and are particularly uncommon in acute lymphoblastic leukemia. We report a case of T-cell acute lymphoblastic leukemia with L2 morphology which demonstrated three cytogenetically distinct clones: 46,XY,t(2;9)(p21;q34)/46,XY,del(6)(q21q23)/47,XX,+8. Interphase cytogenetic analysis by fluorescence in situ hybridization (FISH) confirmed the presence of trisomy 8 in a significant proportion of lymphoblasts, while reverse transcription-polymerase chain reaction (RT-PCR) did not show the presence of BCR/ABL fusion. This is the first report describing the occurrence of cytogenetic triclonality in de novo T-cell acute lymphoblastic leukemia.
