HEMATOLOGY: "BLEEDING" BLOCK

Salam.

dearest faiz, sila tenung betul2.

NORMAL, HAPPY RBCs

1. The red blood cells here are normal, happy RBC's.
2. They have a zone of central pallor about 1/3 the size of the RBC.
3. The RBC's demonstrate minimal variation in size (anisocytosis)
4. and shape (poikilocytosis).
5. A few small fuzzy blue platelets are seen.
6. In the center of the field are a band neutrophil on the left
7. and a segmented neutrophil on the right.

MICROCYTIC, HYPCHROMIC ANEMIA

1. The RBC's here are smaller than normal
2. Have an increased zone of central pallor.
3. This is indicative of a hypochromic (less hemoglobin in each RBC) microcytic (smaller size of each RBC) anemia.
4. There is also increased anisocytosis (variation in size)
5. and poikilocytosis (variation in shape).

MACROBLASTIC ANEMIA

Here is a hypersegmented neutrophil that is present with megaloblastic anemias. There are 8 lobes instead of the usual 3 or 4. Such anemias can be due to folate or to B12 deficiency. The size of the RBC's is also increased (macrocytosis, which is hard to appreciate in a blood smear).
