Definition

Atypical lymphocyte - large nucleus, finer chromatin, and abundant basophilic cytoplasm scalloping around adjacent cells

Term
[image]
Definition

Band - mature nucleus with clumped chromatin but without segmentation

Term
[image]
Definition
Basophil - large dark, red-purple basophilic granules that partially obscure the nucleus
Term
[image]
Definition

Basophilic normoblast - chromatin condensation and deeply basophilic cytoplasm

Term
[image]
Definition

Bone marrow mast cell - numerous uniform purple granules in the cytoplasm that partially obscure the nucleus

Term

Definition

Dwarf megakaryocyte - bilobed nucleus, sometimes seen in the peripheral blood in MDS patients

Term
[image]
Definition

Eosinophilic myelocyte - ovoid nucleus and eosinophilic secondary granules in the cytoplasm

Term
[image]
Definition

Eosinophil - mature eosinophil with bilobed nucleus and large eosinophilic cytoplasmic granules (large chunky orange granules)

Term
[image]
Definition

Large granular lymphocyte - has azurophilic cytoplasmic granules

Term

Definition

Megakaryocyte

Term
[image]
Definition

Metamyelocyte - nuclear indentation and chromatin clumping (indentation is less than 1/2 the nucleus)

Term
[image]
Definition

Monocyte - indented nucleus, linear "ropey" chromatin, basophilic "grey-blue" cytoplasm, and fine azurophilic crystals (red/purple/lilac)

Term
[image]
Definition

Myeloblast - high N/C ration, fine chromatin, visible nucleoli, and basophilic cytoplasm (nucleus is less round than a pronormoblast)

Term
[image]
Definition

Myelocytes - secondary cytoplasmic granules and condenstation of the nuclear chromatin.  The myelocyte on the right is newer with persistent primary granules from the promyelocyte stage.

Term

Definition

Orthochromatic normoblast - pyknotic nucleus and pink-gray cytoplasm

Term
[image]
Definition

Plasma cells - abundant basophilic cytoplasm, eccentric nucleus, and perinuclear hoff (golgi apparatus).  Denim blue jean colored.

Term
[image]
Definition

Polychromatophilic normoblast - light blue cytoplasm due to the accumulation of hemoglobin

Term
[image]
Definition

Promonocytes - linear "ropey" nuclear chromatin often with visible folds and basophilic cytoplasm that may contain vacuoles

Term
[image]
Definition

Promyelocyte - azurophilic granules in the cytoplasm, the chromatin is still fine (cytoplasm still hasn't turned orange, just before the "dawn of neutrophilia")

Term
[image]
Definition

Pronormoblast - large round nucleus, fine chromatin, and basophilic cytoplasm (like all erythroids the nucleus is just plain "round")

Term
[image]
Definition

Reticulocyte - polychromatophilic erythrocyte with pink-gray cytoplasm due to residual RNA

Term
[image]
Definition

Segmented neutrophil - multiple nuclear lobes joined by fine chromatin filaments (6 or more is abnormal = megaloblastic, or greater than 5% with 5 lobes)

Term
[image]
Definition

Small lymphocyte - high N/C ration, condensed chromatin, and scant basophilic cytoplasm (nucleus can be cleaved)
