Description : Myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic stem
cell disorders characterized by ineffective hematopoiesis resulting in low blood counts,
most commonly anemia, and a risk of progression to acute myeloid leukemia (AML; 601626).
Blood smears and bone marrow biopsies show dysplastic changes in myeloid cells, with
abnormal proliferation and differentiation of 1 or more lineages (erythroid, myeloid,
megakaryocytic). MDS can be subdivided into several categories based on morphologic
characteristics, such as low-grade refractory anemia (RA) or high-grade refractory
anemia with excess blasts (RAEB). Bone marrow biopsies of some patients show ringed
sideroblasts (RARS), which reflects abnormal iron staining in mitochondria surrounding
the nucleus of erythrocyte progenitors (summary by Delhommeau et al., 2009 and Papaemmanuil
et al., 2011).;
