Stomatocyte compared to other forms of poikilocytosis.. Hereditary stomatocytosis describes a number of inherited, mostly autosomal dominant human conditions which affect the red blood cell and create the appearance of a slit-like area of central pallor (stomatocyte) among erythrocytes on peripheral blood smear.
Blood smear showing red blood cells with basophilic stippling. Basophilic stippling, also known as punctate basophilia, is the presence of numerous basophilic granules that are dispersed through the cytoplasm of erythrocytes in a peripheral blood smear.
Acanthocytes, from peripheral blood, under light microscopy. Note the irregularly shaped, non-circular cells in the image. Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections.
Scanning electron microscopy (SEM) of echinocytes Echinocyte compared to other forms of poikilocytosis. Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections.
Elevations in target cells are the result of a shift in the exchange equilibrium between the red blood cells and the cholesterol. Also, the surface membrane to volume ratio is increased.
Poikilocytosis is variation in the shapes of red blood cells.Poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted. Normal red blood cells are round, flattened disks that are thinner in the middle
Vos originally described Rh-deficiency syndrome in 1961, when a sample of blood failed to respond with several Rh antisera. However, R. Ceppellini used the term "Rhnull" for the first time.
Neutrophil hypersegmentation can be defined as the presence of neutrophils whose nuclei have six or more lobes or the presence of more than 3% of neutrophils with at least five nuclear lobes. [1]
