Granulated blasts have a size of 12 - 16 µm and show significant reddish granules in their cytoplasm. The shape of the nucleus is round or oval with a very high nucleocytoplasmic ratio of 70 – 95%.
The chromatin is predominantly regularly distributed and neither clumped nor condensed. The nucleus has a varying number of nucleoli which may be hidden by the chromatin.

Cell description:
Size: larger than normal lymphocytes
Nucleus: round, oval, dumbbell-shaped or bilobed with little chromatin condensation and sometimes indistinct nucleolus
Cytoplasm: abundant weakly basophilic with irregular “hairy” margins

Hairy cell from a hairy cell leukaemia. Typical are the monocytic type nuclei with loose chromatin, and the grey-blue, heterogeneous cytoplasm. The hairy protrusions may be missing in some cases.
