Neutrophilic bands are characterized by further constriction of the nucleus causing it to
have the shape of a curved rod. The chromatin is condensed, and the cytoplasm resembles that of a
mature neutrophil.

Neutrophil
unusual nuclei that consist of 2-5 lobes that are attached to one another by fine threads of chromatin
cytoplasm appears a salmon-pink color in a Romanovsky stained blood smear
salmon pink and reddish purple grnaules
This cell has a weird nucleus, as you know: it has hot-dog-link segments with pinched, narrowed strands of nucleus between the segments

neutrophil

EOSINOPHILS
same size as neutrophils
large, spherical, eosinophilic granules.
nucleus of eosinophils is typically bilobed
The granules in eosinophils are beautiful – they are large, luminous, and reddish-orange. The word eosin comes from the Greek word eos, which means “flush of the dawn sky.
The nucleus is nothing to write home about, really – it’s segmented into a few different parts, and it looks kind of like a neutrophil nucleus.

SMALL/MEDIUM LYMPHOCYTE
intensely staining, spherical nucleus surrounded by a thin rim of pale blue cytoplasm.
The medium lymphocyte is about 8-10 µm in diameter. Its cytoplasm is more abundant, and its nucleus is larger and less heterochromatic than that of the small
lymphocyte.

LARGE LYMPHOCYTE
The large lymphocyte is about 10-18 µm in diameter. Its nucleus is even less heterochromatic than that of the medium lymphocyte.
In some large lymphocytes one can also
observe azurophilic granules within their cytoplasm. These are the natural killer (NK) cells.

relatively large cells, from 10-15 µm in diameter.
The nucleus of a

Neutrophilic promyelocytes
spherical nuclei in which the chromatin is a little bit
more condensed than that of blasts. Nucleoli can often be observed
The cytoplasm of these cells is characterized by the presence of large, azurophilic granules (primary granules).

BASOPHILE
Basophil nuclei are irregular in shape but less segmented than those of
the other granulocytes. This will be difficult for you to see because of the presence of large
cytoplasmic granules that usually obscure the nucleus. These granules stain intensely with azure B
and appear a deep violet in a typical blood smear.

Blasts (myeloblasts)
The nucleus of a
blast is large and euchromatic, and several nucleoli can often be observed within it. The cytoplasm
appears pale blue, and there will be no granules present. A blast has a large nucleocytoplasmic ratio.

Basophilic erythroblast (BE)
In addition, nuclear chromatin is more condensed.
Typically what you will see is a
speckled nucleus.
The cytoplasm of this cell will be intensely basophilic (navy blue)
There will be alternating areas of diffuse and compact chromatin, which gives the
nucleus a “checkerboard” appearance.
The nucleoli will often be obscured by the condensed
chromatin.
Basophilic erythroblasts are a bit smaller than blasts, and their nuclei are also smaller than
those of blasts.

Polychromatophilic erythroblasts are even smaller cells, and their nuclei are more
condensed. Due to the accumulation of hemoglobin in these cells, their cytoplasm will display both
basophilia and eosinophilia at the same time. It will shift from blue gray to gray as the cell matures.
Frequently, polychromatophils cluster around reticular cells

Normoblasts are smaller than polychromatophils. Their nuclei are also smaller and totally
condensed.
The cytoplasm of a normoblast is still faintly polychromatophilic (mostly pink with a
touch of blue).

Orthochromatic erythroblasts (normoblast)
ose their residual RNA before they extrude their nuclei.
Therefore, this cell will have a small, heterochromatic nucleus surrounded by bright eosinophilic
cytoplasm.It will look just like a mature erythrocyte with asmall condensed nucleus. These cells
are normally not released into the peripheral circulation.
