Stomatocyte may also be artefactual and should be suspected when less than 10% of red cells are stomatocytes.
Non-spiculated variants include target cells, ovalocytes and stomatocytes.
Stomatocyte Haemolysis: Stomatocytes are RBCs with a defect in their membranes that causes the cells to assume a mouth or stoma-like shape.
Two of these disorders are characterised by the presence of malformed RBCs-- stomatocytes and spur cells--whereas one alcohol-related haemolytic anaemia is caused by reduced phosphate levels in the blood (i.
Moreover, microscopic examination of blood films obtained from naturally infected cases showed presence of parasite and various morphological changes in cells such as
stomatocyte, hypochromia and polychromia.
Hydroxyurea-induced
stomatocytes in a patient presenting with polycythemia vera.
The activity of betulinic acid and some of its analogues - betulinic aldehyde, lupeol, betulin, methyl betulinate, and betulinic acid amide has been studied on their ability (according to their hydrogen bonding properties) to cause changes in erythrocyte membrane shape towards formation of
stomatocytes or echinocytes.

These include
stomatocytes, red blood cells with a comb, there are also other irreversible pathological forms of erythrocytes (Figure 4).
Marked changes in the shape of RBC from normal discocytes to echinocytes, spherocytes,
stomatocytes and acanthocytes were also observed in the blood of the rats treated with (131)I.
The abnormalities seen on the smears examined revealed the presence of nucleated red cells, basophilic stipplings, Target cells,
Stomatocytes and Tear drop cells.
Section II discusses the specifics of grading individual red blood cell abnormalities and defines a grading system described in words and images for anisocytosis, poikilocytosis, microcytosis, macrocytosis, hypochromia, polychromasia, blister cells, target cells, teardrop cells, schistocytes, sickle cells, spherocytes, acanthocytes, echinocytes, elliptocytes,
stomatocytes, Howell-Jolly bodies, basophilic stippling, Pappenheimer bodies, rouleaux, and agglutination.
