Sideroblastic anemia is a disease where the bone marrow produces abnormal red blood cells called ringed sideroblasts that contain iron deposits around the nucleus, rather than healthy red blood cells. It can be caused by genetic disorders, myelodysplastic syndrome, or certain toxins and medications. Patients experience symptoms of pale skin, fatigue, and enlarged organs. The disease is diagnosed through identification of ringed sideroblasts in bone marrow samples and blood tests showing iron overload. Treatment depends on the severity of anemia and underlying cause, and may include blood transfusions, high dose vitamin supplements, chelation therapy to remove excess iron, and in severe cases, bone marrow transplant.
