Overview

Pancytopenia is described as a decrease in the 3 cell lines which are red blood cells, white blood cells and platelets. Clinically, pancytopenia is defined as hemoglobin< 9gm, white blood cell count< 4,000/cmm and platelets < 100,000/cmm. It can be due to decreased production in the bone marrow or increased destruction of cells in the periphery. Pancytopenia can also be caused due to drugs such as chemotherapy agents. Treatment involves identifying the underlying cause and appropriate therapy.
