Pure Red Cell Aplasia

pure-red-cell-aplasia

Background: Pure red cell aplasia (PRCA) is an uncommon disorder in which maturation arrest occurs in the formation of erythrocytes. Erythroblasts are virtually absent in bone marrow; however, WBC and platelet production is normal. The anemia due to PRCA is usually normocytic but can be macrocytic. The characteristics of PRCA include severe anemia, a reticulocyte count <1%, and the presence […]

This causes a deficiency of all three blood cell types (pancytopenia): red blood cells (anemia), white blood cells (leucopenia), and platelets (thrombocytopenia). Aplastic refers to the inability of the stem cells to generate mature blood cells. Aetiology: Congenital: The […]

Megaloblastic Anemias

Iron Deficiency Anemia

Introduction: Megaloblastic anemias are a group of disorders characterized by reduced DNA synthesis (not just in red cell series) associated with pathognomonic morphological changes. When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M) stage. This leads to continuing cell growth without division, which presents as macrocytosis. In other words, megaloblastic anemia […]
