in a Case of Liver Disease
The highest rate of misclassification occurred with dacrocytes and acanthocytes
, both of which were predominantly misclassified as schistocytes (Table 2).
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).
Distinguished from other species of Stropharia by the smooth and dark brown pi leus, abundant veil remnants on the pileus margin, basidiospores 10.5-13 X 6.5-8 [micro]m, pleuro- and cheilocystidia as chrysocystidia, and presence of scattered acanthocytes
in the hymenium and stipe apex.
The presence of acanthocytes
is evidenced as abnormal projections on the red blood cells.
The causes of thrombocytosis could be multiple such as myeloproliferative disorders, reactive or secondary thrombocytosis or Hyposplenism or Post splenectomy.2 Hyposplenism (or asplenia or autosplenectomy) is defined as underfunctioning of the spleen which may or not be associated with a reduction in splenic size.3 The normal functions of the spleen are reduced to a varying degree in a number of illnesses including systemic lupus.3 Hyposplenism is characterized clinically by leukocytosis, thrombocytosis, presence of Howell jolly bodies, erythrocytes pits and acanthocytes
on peripheral smear.
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.
Crenated erythrocytes can also resemble acanthocytes
that are associated with certain lipid disorders.
rugosoannulata J2 were trapped by acanthocytes
which can be seen in Fig.
Neuroacanthocytosis is a cause of chorea in children and can be diagnosed by a fresh peripheral blood smear examination showing acanthocytes
in the smear.
Our patient, however, showed no evidence of malabsorption, retinitis pigmentosa, or neurologic disease, and there was no evidence of acanthocytes
. The mild clinical phenotype strongly suggested the clinical diagnosis of heterozygous FHBL.
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.
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., 2007; Zouhar et al., 2013).
