ICD-11 definition : Hereditary elliptocytosis is a group of rare conditions caused by abnormalities in
the red cell cytoskeleton and marked by the presence on blood smears of numerous elliptical
red blood cells, called elliptocytes. Clinical presentations are highly heterogeneous
ranging from asymptomatic forms to more severe forms associated with variable anemia,
from moderate to severe and with pyropoikilocytosis including fragmented red cells,
microelliptocytes and microspherocytes.;
