Eosinophilic Myelocytes may be found in large numbers, varying from 3000 to 100,000 per cubic millimeter. Such an increase is pathognomonic of splenomyelogenous leukemia. The ordinary type of eosinophiles is also increased.
Basophiles or mast-cells are increased, sometimes very markedly, this condition being quite characteristic of the leukemia.
