Down syndrome with different hematological manifestations: a short series of 3 cases with review of literature

Children with Down syndrome (DS) present with a spectrum of hematolymphoid malignancies ranging from transient myeloproliferative disorder (TMD) which regress spontaneously to frank acute leukemia of both myeloid and lymphoid lineage. Here we present a series of three cases with different manifestation in DS. Three cases of DS presented with TMD, acute myeloid leukemia (AML-M2) and acute megakaryoblastic leukemia (AMKL), respectively. This case series displays the spectrum of hematological manifestations in children with DS. Although TMD and AMKL are strongly associated with DS, other AML subtypes can also be seen in such patients.
