Tetraploidy or near-tetraploidy clones with double 8;21 translocation: a non-random additional anomaly of acute myeloid leukemia with t(8;21)(q22;q22)

We report on 6 patients with tetraploidy or near-tetraploidy acute myeloid leukemia (AML) with double t(8;21) (q22;q22) and review the literature on cases with the same cytogenetic abnormalities. Some common features were revealed by this analysis.
