Howell-Jolly bodies are nuclear remnants within red cells that are ordinarily removed by the spleen. They are usually single, round, dark purple-red in color and peripheral in location. The presence of Howell-Jolly bodies most frequently indicates either absence of the spleen (eg, surgical removal) or splenic hypofunction (eg, sickle cell disease) 

Isomerism: 就是胸腹部的器官對稱(正常人不對稱)
RAI:左右都長右邊,可能會合併無脾臟

都有可能cyanosis
