6 Severe anisocytosis; the MCV was 133 fl but the macrocytosis is not uniform. Assessing red cell shape (poikilocytosis) If red cells show more than the normal degree of variation in red cell shape there is said to be poikilocytosis (Fig. 10). Assessing Red Cells Fig. 7 Microcytic red cells (MCV 62 fl). Fig. 8 Normocytic red cells. Fig. 9 Macrocytic red cells (MCV 105 fl). 33 Fig. 10 Severe poikilocytosis; cells vary considerably in shape but no single shape dominates. ) Normal cell Elliptocyte Spherocyte Ovalocyte Micro-spherocyte Irregularly contracted cell Dacrocyte (tear-drop poikilocyte) Target cell Stomatocyte Keratocyte Schistocyte (fragment) Echinocyte (crenated cell) Acanthocyte Sickle cell Boat-shaped cell S-C poikilocyte Fig.

Fig. 20 Acanthocytes (in abetalipoproteinaemia). Assessing Red Cells 39 Fig. 21 One sickle cell and several boat-shaped cells (in sickle cell anaemia). Fig. 22 SC poikilocytes (in sickle cell/haemoglobin C disease). Assessing red cell colour (hypochromia, hyperchromia, anisochromasia, polychromasia) Normal red cells are reddish-brown with approximately the central third to quarter of the cell being paler. They are described as Fig. 23 A population of severely hypochromic cells with only a thin rim of haemoglobinized cytoplasm (in refractory anaemia with ring sideroblasts); there are other cells which stain normally and the film is therefore described as dimorphic.

Macropolycytes are likely to have 92 Fig. 6 A neutrophil with two very round lobes in a patient with the congenital Pelger–Huët anomaly. 50 Chapter 3 Fig. 7 A hypersegmented neutrophil in a patient with megaloblastic anaemia. The neutrophil nucleus has seven lobes. Fig. 8 A macropolycyte compared with a normal neutrophil. The macropolycyte is twice as large as the normal neutrophil and has a nucleus with seven or eight lobes which is also twice as large as a normal neutrophil nucleus. e. they are likely to be tetraploid rather than diploid.
