Overview
Differential Diagnosis
Sideroblastic anemia must be differentiated from other causes of microcytic hypochromic anemia: iron deficiency anemia, thalassemia, anemia of chronic disease, lead poisoning, and blood loss.
• Tissue iron overload from sideroblastic anemia may act similar to hereditary hemochromatosis with liver cirrhosis, diabetes, congestive heart failure, and cardiac arrhythmias.
- ALA Dehydratase Deficiency Porphyria
- Acute Myeloid Leukemia (AML)
- Congenital Erythropoietic Porphyria
- Hereditary Coproporphyria
- Iron Deficiency Anemia
- Myelodysplastic Syndrome
- Secondary Thrombocytosis
On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].
