Macrocyte
From Wikipedia, the free encyclopedia
A macrocyte is an exceptionally large red blood cell occurring chiefly in anemias (as in pernicious anemia), they are also present in some cases of aplastic anaemia, myelodysplastic syndrome and other dyserythropoietic states. A common cause of macrocytosis is excess alcohol intake and it occurs in alcoholic and other types of chronic liver disease. In one rare form of congenital dyserythropoietic anaemia (typeIII), some of macrocytes are exceptionally large. Another rare cause of macrocytosis is benign familial macrocytosis. Macrocytosis also occurs when there is an increase rate of erythropoiesis because of the presence of reticulocytes [1].
