ABSTRACT
Background: Pancytopenia is defined as reduction of all three formed elements of blood below normal reference range. The symptoms are fatigue, fever, dizziness and weight loss. Evaluation was done using complete hemogram and peripheral smear. The presenting marrow biopsy is most useful and accurate in evaluation of pancytopenia.Methods: Two ml of anticoagulated blood was collected for complete hemogram. The peripheral blood smear was stained with Leishman's stain and studied. Bone marrow biopsy and aspiration was done in all the patients to identify etiology.Results: Predominance was seen in the age group of 31-60 years. Most common cause of pancytopenia was megaloblastic anaemia in this study compared to other studies all over the world where most common cause was aplastic anaemia. This reflects higher prevalence of megaloblastic anaemia in the Indian subjects.Conclusions: A comprehensive clinical, haematological land bone marrow study of patients with pancytopenia usually helps in identification of the underlying cause.
