Macrocytosis is a condition where red blood cells are larger than normal. [1] These enlarged cells, also known as macrocytes, are defined by a mean corpuscular volume (MCV) that exceeds the upper reference range established by the laboratory and hematology analyzer (usually >110 fL). [2]
Macrocytic anemia is a condition and blood disorder characterized by the presence of predominantly larger-than-normal erythrocytes (red blood cells, or RBCs) accompanied by low numbers of RBC, which often carry an insufficient amount of hemoglobin.
Megaloblastic anemia is a type of macrocytic anemia.An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2]
Macroovalocytes are enlarged, oval-shaped erythrocytes (red blood cells). They are not seen in healthy blood, and are most commonly seen in megaloblastic anemia. [1] In most instances, the macroovalocyte morphology is due to megaloblastic erythropoiesis (Vitamin B-12 or folate deficiency) but may be seen with dyserythropoiesis.
Dacrocytes (teardrop cells) Dacrocytes compared to other forms of poikilocytosis A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell").
Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation (poly- refers to many, and -chromasia means color.)
Pappenheimer bodies are visible with a Wright and/or Giemsa stain. Confirmation of non-heme iron in the granules is made with a Perls' Prussian blue stain, and this atypical red blood cell is then known as a siderocyte. [5]
This kind of anemia leads to macrocytes (abnormally large red cells) and the condition called macrocytosis. The cause of this cellular gigantism is an impairment in DNA replication that delays nuclear maturation and cell division .
