Presentation
We present two cases of congenital sideroblastic anemia with their clinico-hematological profile. Case 1 A 1.5 year-old-male child presented in the outpatient department of hematology with complaints of pallor since birth. [ijpmonline.org]
Patients of CSA presents with hereditary hypochromic anemia which is apparently not due to iron deficiency or thalassemia. The two infants in this report presented at an early age with pallor and hepatospleno-megaly. [indianpediatrics.net]
Patients can present at any age with symptoms of anemia or iron overload. 4, 11 Physical examination is unremarkable although mild hepatosplenomegaly may be present. [clinicalgate.com]

Prognosis Prognosis is variable but for patients with pyridoxine-responsive anemia whose iron stores are kept low, normal life expectancy should be achievable The documents contained in this web site are presented for information purposes only. [orpha.net]
Few patients are eligible for transplant. [ 1 ] Prognosis [ 9 ] The prognosis is very variable. Reversible causes (eg, alcohol or drugs) appear to have no long-term effects if the underlying cause is successfully treated or removed. [patient.info]
Course and prognosis Sideroblastic anemia’s are often described as responsive or non-responsive in terms of increased Hb level to pharmacological doses of vitamin B6. 4. بالتوفيق لي ادعو Page 4 [slideshare.net]
