Medical Intelligence & Overview
Secondary sideroblastic anemia is a type of anemia caused by exposure to certain drugs or toxins that interfere with the body's ability to produce healthy red blood cells. This condition is characterized by the presence of ring sideroblasts—abnormal red blood cell precursors with iron-loaded mitochondria—found in the bone marrow. When caused by external substances such as drugs or environmental toxins, it is classified under ICD-10 code D64.2. Understanding the causes, symptoms, diagnosis, and treatment options can help in managing this condition effectively.
