Identification of cells

This presentation describes the identification of cells.

1. IDENTIFICATION OF CELLS PRESENTED BY SYED BASHEER UDDIN

2. Small Lymphocyte 7-8 microns Round or kidney-shaped nucleus, diffusely lumpy to compact chromatin structure Narrow cytoplasm edge, light blue

3. Large lymphocyte 9-15 microns Oval/bulging nucleus, somewhat looser chromatin structure than the small lymphocyte. No nucleolus Plentiful colorless to light blue cytoplasm

4. Neutrophil 12-15 microns Nucleus with coarse, clumped chromatin structure with 3-5 segments Plentiful pale pink to colorless cytoplasm Moderate to plentiful very fine pink granules

5. Eosinophil 12-17 microns Nucleus with coarse, clumped chromatin structure with 2-3 segments Cytoplasm nearly invisible due to the granulation, Plentiful large, round brick-red granules

6. Monocyte 12-24 microns Kidney-shaped, bulging or segmented nucleus. Plentiful, grey cytoplasm Possible powder-fine, violet granules Vacuoles often appear in the cytoplasm

7. Basophil 10-15 microns Nucleus with diffuse, clumped chromatin structure with 3-4 poorly defined segments Plentiful pale pink to colorless cytoplasm Moderate to plentiful, unevenly sized, round, bluish-black granules

8. Atypical lymphocyte/Reactive lymphocyte Size about - 15 - 30 µm or more Nucleus: Large irregular Cytoplasm: Plentiful, deep blue color Moulding of the adjacent RBCs

9. Myeloblast 10-20 microns Large round to oval nucleus Fine evenly stained chromatin structure 2-5 nucleoli Relatively small to moderate amount of pale blue cytoplasm with clear zone closest to the nucleus

10. Macrocytes Erythrocytes larger than 8.5 microns in diameter are called macrocytes . They are thicker and stain deeper than normocytes . They are found in megaloblastic anemias , liver disease, hemolytic anemias and sometimes in diabetes.

11. Microcytes Erythrocytes smaller than 6.5 microns are called microcytes . They can be seen in iron deficiency anemia, Sideroblastic anemia, thalassemia etc.

12. Spherocyte Small deeply staining cells without central pallor. They are found in Hereditary spherocytosis and in hemolytic anemias .

13. Target Cells Target cells, also known as Codocytes . They have the hemoglobin concentrated in the middle and the periphery of the cell, and thereby resemble targets. They can be seen in thalassemias , iron deficiency anemia and in liver disorders.
