aplastic anemia

https://doi.org/10.1351/goldbook.12902
Greatly decreased formation of erythrocytes and hemoglobin, usually associated with pronounced granulocytopenia and thrombocytopenia, as a result of hypoplastic or aplastic bone marrow.
Note: The diagnosis requires bone marrow biopsy to demonstrate replacement of blood cell precursors with fat cells and rule out other causes of pancytopenia such as neoplastic infiltration.
