Trisomy 6 as Sole Cytogenetic Abnormality in Acute Myeloid Leukemia 'A Case Series'

Identification of cytogenetic abnormalities plays an important role in the diagnosis and prognosis of leukemias. We report three cases of trisomy 6 as sole cytogenetic abnormality in acute myeloid leukemia (AML). Short-term unstimulated bone marrow culture showed two cases of AML-M1 and one case of AML-M2 with trisomy 6. It is known that trisomy 6 is a rare numerical abnormality and prognostic significance is not well established. More studies are required to assign the role of trisomy 6 in the development of leukemia as well as in prognosis.
