Development of leukemia in patients with sexual chromosome abnormalities is relatively rare and mostly involves cases of monosomy X, Turner syndrome. Here, we report on a child having a 45,X/46,X,derY [?t(Yp;Yq)] chromosomal constitution (variant Turner syndrome) presenting with concordant acute myeloid leukemia and a rarely seen clonal neoplasic cell lineage-related karyotype, t(6;9)(p23;q34).
