The term poikilocytosis refers to a condition where 10% or more of the red blood cells are abnormally shaped due to other medical conditions. Dacrocytosis is often associated with other red blood cell morphologic abnormalities, such as anisopoikilocytosis and the presence of schistocytes (fragmented red blood cells).
