Transcript of SADT Leukemias
Leukemias - Normal Blood Smear, Chronic Lymphocytic Leukemia and Chronic Granulocytic Leukemia
First study the normal blood smear. Note the relative abundance of red blood cells and white blood cells. Neutrophils are the most common type of WBC in normal blood.
Normal blood (100X2.0)
Two WBCs (blue dots) and many RBCs
Normal blood - WBCs are dark(100X2.8)
TwoWBCs (lymphocyte at left, neutrophil at far right) and many RBCs
Now study the smear from a patient with chronic lymphocytic leukemia. Note the relative abundance of RBCs and WBCs (observing a number of fields) and note that almost all the WBCs are lymphocytes.
Lymphocytic leukemia (100X2.0)
Many WBCs (dark dots), which are lymphoctes
Lymphocytic leukemia (400X2.3)
Four WBCs, all of which are lymphocytes
On the slide of the chronic granulocytic leukemia, note that there are more WBCs than RBCs and that the WBCs are abnormal in size, shape and nuclei. Compare these WBCs with those in the normal blood smear.
Granulocytic leukemia (100X2.8)
WBCs (blue cells) are extremely numerous, RBCs are much less numerous than in normal
Granulocytic leukemia (400X2.3)
WBCs (blue cells) are numerous and many are dysplastic blood
(i.e., have abnormal stucture {e.g., abnormally large, large nuclei})
