In a previous paper,1 serum concentrations of vitamin B12 in patients suffering from chronic leukemia were reported. It was shown that, in chronic lymphocytic leukemia, serum contains a normal concentration of the vitamin, whereas in chronic myelocytic leukemia the concentration is markedly increased.
A preliminary report of serum vitamin B12 concentrations in seven cases of acute leukemia suggested that the variable concentrations found might be associated with morphologic differences in cell types such as occur in chronic leukemia. In this paper a morphologic diagnosis has been attempted in 20 cases of acute leukemia, and comparison made with the serum vitamin
