The myelodysplasia syndromes (MDS) are clonal stem cell disorders characterized by progressive cytopenia or cytopenias, usually in the presence of a hypercellular bone marrow and multilineage dysplasia. Usually, all 3 cell lines (myeloid/monocyte, erythroid, megakaryocyte) are involved. Myelodysplasia syndrome is rare in childhood, and most children have a rapidly progressive course. Myelodysplasia disorders have been defined by their predilection to evolve into acute myeloid leukemias (AML), yet not all cases terminate in leukemia.
