Investigation of poikilocytic normochromic normocytic anemia. 1. Round and elongated forms. 1979

P C Ward

Occasional nonspecific poikilocytes are found in most normal blood smears, but dominance of one or more forms of poikilocytes usually is indicative of a specific anemia or disease in an organ or organ system. For example, stomatocytes are most commonly associated with acute alcoholism, while teardrop cells classically reflect "spent" polycythemia vera or myelofibrosis. The clinical significance of the various round poikilocytes (spherocytes, stomatocytes, target cells) and elongated poikilocytes (ovalocytes and elliptocytes, teardrop cells, sickle cells) is discussed.

D013103	Spherocytosis, Hereditary	A group of familial congenital hemolytic anemias characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. The erythrocytes have increased osmotic fragility and are abnormally permeable to sodium ions.	Hereditary Spherocytoses,Spherocytoses, Hereditary
D013789	Thalassemia	A group of hereditary hemolytic anemias in which there is decreased synthesis of one or more hemoglobin polypeptide chains. There are several genetic types with clinical pictures ranging from barely detectable hematologic abnormality to severe and fatal anemia.	Thalassemias
D055728	Primary Myelofibrosis	A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.
