Spherocytosis most often refers to hereditary spherocytosis. This is caused by a molecular defect in one or more of the proteins of the red blood cell cytoskeleton, including spectrin, ankyrin, Band 3, or Protein 4.2. Because the cell skeleton has a defect, the blood cell contracts to a sphere, which is its most surface tension efficient and The hematologic hallmark of sickle cell disease is the irreversibly sickled cell (ISC) a shrunken, dehydrated cell which resists hypotonic lysis. Less well recognized in sickle cell disease is In cases of congenital spherocytosis in association with sickle trait, spherocytes are present in the peripheral blood smear and there is an absence of sickle forms.

Spherocytosis vs sickle cell

A normal red blood cell can live for up to Risk factors for pigment stones include chronic hameolysis (red blood cell breakdown) -hereditary spherocytosis, sickle cell disease, as well as liver cirrhosis. [myvmc.com] Introduction: The prevalence of choledocholithiasis among patients with acute cholecystitis is estimated to be between 9 and 16.5%.

The defect causes the red blood cell to have a spherical or round shape. The change in shape makes these red blood cells break down more quickly than normal red blood cells. Hereditary spherocytosis and hereditary elliptocytosis are congenital red blood cell (RBC) membrane disorders that can cause a mild hemolytic anemia.

The rare combination of sickle cell trait with hereditary spherocytosis in a Sudanese family is reported. The splenic hypofunction and fibrosis as a result of sickling has ameliorated the clinical course of the 35 year old father. Spherocytosis can be diagnosed in Peripheral blood film by seeing spherical red blood cells rather than biconcave. Because spherical red blood cells are more prone to lysis in water (because they lack some proteins in their cytoskeleton) there will be increased osmotic fragility on acidified glycerol lysis test.
