Pure red cell aplasia (PRCA) or erythroblastopenia refers to a type of aplastic anemia affecting the precursors to red blood cells but usually not to white blood cells. In PRCA, the bone marrow ceases to produce red blood cells. There are multiple etiologies that can cause PRCA. The condition has been first described by Paul Kaznelson in 1922. [1]
Aplastic anemia is a rare, noncancerous disorder in which the blood marrow is unable to adequately produce blood cells required for survival. [44] [45] It is estimated that the incidence of aplastic anemia is 0.7–4.1 cases per million people worldwide, with the prevalence between men and women being approximately equal. [46]
Aplastic anemia, paroxysmal nocturnal hemoglobinuria, myelodysplasia, leukemia Agranulocytosis , also known as agranulosis or granulopenia , is an acute condition involving a severe and dangerous lowered white blood cell count ( leukopenia , most commonly of neutrophils ) and thus causing neutropenia in the circulating blood.

Aplastic anemia is a condition where bone marrow does not produce sufficient new cells to replenish blood cells. [27] Autoimmune hemolytic anemia: D59.0-D59.1: Autoimmune hemolytic anemia (AIHA) is a type of hemolytic anemia where the body's immune system attacks its own red blood cells (RBCs), leading to their destruction .
The following is a differential diagnosis for patients in which reticulocytopenia is the most marked cytopenia. For conditions that lead to significant reduction in all three cell lineages, see pancytopenia or aplastic anemia. Parvovirus B19 infection [5] Transient Erythroblastopenia of Childhood [4] Pure red cell aplasia [6]
The mechanism of pancytopenia involves either haemopoiesis itself, decreasing blood cell productions in number (aplastic anemia), haemopoietic stem cells are displaced by malignant cells (Leukemia, lymphoma, MDS) or they are being pooled (sequestrated) (spleen)/destroyed (immune) outside bone marrow.
Aplastic anemia patients present with symptoms related to a decrease in hematopoietic cell production in the bone marrow. The onset is gradual, and the first symptom is frequently anemia or bleeding, though a high temperature or infections may be present at the onset. The following are examples of specific manifestations: [12]
It is mainly used to differentiate an anemia of mixed causes from an anemia of a single cause. Deficiencies of Vitamin B 12 or folate produce a macrocytic anemia (large cell anemia) in which the RDW is elevated in roughly two-thirds of all cases. However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and ...
