Medical Intelligence & Overview
Refractory anemia with ring sideroblasts (RARS) is a type of myelodysplastic syndrome (MDS), a group of disorders caused by poorly formed or dysfunctional blood cells. Characterized primarily by anemia, RARS involves the presence of abnormal red blood cell precursors called sideroblasts, which contain iron-loaded hemosiderin granules that encircle the nucleus in the bone marrow. Unlike other forms of anemia, RARS does not respond well to standard treatments and tends to progress slowly, but it can develop into more severe blood disorders or leukemia over time.
