Serum vitamin B12 level in infants is determined by the foetal storage during pregnancy. Therefore, evaluation on vitamin B12 level during pregnancy is essential for prevention of vitamin B12 deficiency in infancy. Here we report a vitamin B12 deficient infant who presented with hepatosplenomegaly with pancytopenia including normocytic anaemia and circulating atypical cells.
