/an·iso·cy·to·sis/ (-si-to´sis) presence in the blood of erythrocytes showing excessive variations in size.

anisocytosis

[anī′sōsītō′sis]
Etymology: Gk, anisos + kytos, cell
an abnormal condition of the erythrocytes characterized by variable diameter on a blood film and associated with increased red cell distribution width (RDW). Compare poikilocytosis. See also macrocytosis, microcytosis.

anisocytosis

Inequality in the size of red blood cells found in many kinds of ANAEMIA but especially in MEGALOBLASTIC anaemia.
