Pediatric Hereditary Oval Polycythemia

Hereditary elliptocytosis (HE) is another type of hemolytic anemia with defective red blood cell membranes. The characteristic of this disease is that a large number of ovals can be seen in the surrounding blood to form mature red blood cells. Clinical symptoms vary in severity, and the most severe cases can die in the uterus due to fetal edema. A few oval red blood cells can also be seen in normal human blood, generally no more than 15%. In this case, these red blood cells are above 25%. According to the degree of hemolysis, there are 3 types: no hemolysis (concealed type), mild hemolysis (hemolytic compensation type), and significantly accelerated hemolysis type.
