Presentation Transcript

  1. Blood Smear

  2. This peripheral blood smear from a patient with essential thrombocythemia shows increased numbers of platelets, including some large forms. (H and E, 400x)

  3. Malaria

  4. Atypical, or reactive, lymphocytes

  5. Acanthocytes (red arrow) and schizocytes (black arrow) in a canine blood smear

  6. Keratocytes in a canine blood smear

  7. Band neutrophil

  8. Vacuolated monocyte

  9. Lymphocyte with azurophilic granules

  10. Hypersegmentation

  11. Toxic granulation

  12. Döhle body

  13. Platelets - finger-stick

  14. Giant platelet

  15. Nucleated Red Blood Cells

  16. Macrocytic Red Blood Cells Compared to Normal Red Blood Cells

  17. Promyelocyte

  18. Segmented Neutrophil, Metamyelocyte, Band

  19. Sickle Cell Anemia

  20. Pernicious Anemia

  21. Plasma cell

  22. Hairy cell

  23. Larger than average RBCs are macrocytic (left), while those smaller than average are microcytic (right).

  24. Pale cells (central pallor >1/3 dia) are referred to as hypochromic (right), while cells without central pallor are called hyperchromic (left).

  25. SCHISTOCYTES

  26. TARGETS

  27. OVALOCYTES

  28. STOMATOCYTES

  29. SPHEROCYTES

  30. ACANTHOCYTES

  31. BURR CELLS

  32. Elliptocytosis

  33. Tear Drop Cells

  34. Rouleaux Formation

  35. Basophilic stippling

  36. Howell-Jolly Bodies

  37. Platelet Clumping

  38. Auer Rods

  39. With iron deficiency anemia, the MCV of the red blood cells is decreased, the zone of central pallor is increased, and the overall sizes and shapes of the RBC's are less uniform (increased anisocytosis and poikilocytosis ).

  40. Heinz bodies (red arrows) and nucleated red blood cells (purple arrows) in scattered erythrocytes of a dog with zinc toxicosis (Dog, blood smear, Wright-Leishman stain).

  41. Spherocytes (red arrows) and nucleated red blood cells (purple arrows) in the blood smear of a dog with zinc toxicosis (Dog, blood smear, Wright-Leishman stain).
