Lymphoblast
-Usually round to oval cells with round to oval nuclei which may occasionally be cleft.

-Nuclei often contain nucleoli and the chromatin is typically fine and lacy (but less so than in myeloblasts).

-The N:C ratio varies from 7:1 to 4:1.

-The cytoplasm varies in quantity, stains moderately basophilic and usually agranular (vacuoles may be present).

-Note: In absence of cytochemistries or flow cytometery, blasts cells cannot be differentiated by cell line.
