For diagnosing neuroacanthocytosis syndromes, detection of acanthocytes
in the peripheral blood is an important criterion; however, since the presence of acanthocytosis alone is not significant, there should be accompanying clinical findings (4).
2006) which produce specialized structure of large spike cell called acanthocytes
(Farr, 1980), which mechanically destroy nematodes eggs as well as J2.
5-8 [micro]m, pleuro- and cheilocystidia as chrysocystidia, and presence of scattered acanthocytes
in the hymenium and stipe apex.
Our patient, however, showed no evidence of malabsorption, retinitis pigmentosa, or neurologic disease, and there was no evidence of acanthocytes
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.
Poikilocytosis is moderate to severe with burr cells, acanthocytes
, and schistocytes present.
oviparasitica produce adhesive networks, large spike cells called acanthocytes
, and adhesive knobs or non-constricting rings, respectively (Jansson and Nordbring-hertz, 1979; Lopez-LIorca et al.
The hematuria is considered glomerular in origin when [greater than or equal to] 40 percent of at least 100 urinary RBC are dysmorphic, or [greater than or equal to] 5 percent are proven to be acanthocytes
via phase contrast microscopy.
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.
Other clinical manifestations are serum [alpha]-tocopherol concentrations below or at the lower limit of the reference interval and abnormal erythrocyte morphology with characteristic acanthocytes
, as seen in persons with vitamin E deficiency (4).
In the interest of simplifying reports and eliminating redundant information given to clinicians, some laboratories have moved to eliminating the non-specific term poikilocytosis and reporting only the specific type of abnormal RBC forms, (2) such as spherocytes, acanthocytes
, and teardrops.
