Introduction: The study was done to know the spectrum of hematological disorders. Materials and Methods: This was a retrospective and prospective study of bone marrow aspiration (BMA) and biopsies done on patients who were referred for bone marrow examination. Cases were analyzed in detail regarding clinical examination and other investigations. Results: BMA from 110 patients were analyzed. Nutritional anemia contributed highest number of cases among the nonhematological group. Out of nutritional anemia megaloblastic anemia was the most common disorder. Acute myeloid leukemia was the commonest malignant hematological disorder in the present study. Among 110 cases 56 cases were male and 54 were female patients with highest number of cases in the age group of 21-30 years. Conclusion : Although bone marrow examination is an invasive procedure this is well tolerated by patients. The examination helps in many cases to arrive at a final diagnosis within a short span of time.
Keywords: Bone marrow, malignant hematological disorders, non malignant

| Introduction|| |
Hematological disorders are quite frequent in population. Most of the times the diagnosis can be arrived by detail clinical examination and few simple investigations. However without bone marrow examination the diagnosis is usually not confirmed. Bone marrow aspiration (BMA) examination is one of the most frequent and relatively safe invasive procedure. Though an invasive procedure it can be easily performed even in the presence of thrombocytopenia with little or no risk of bleeding.  Biopsy of bone marrow is an adjunct to the study of hematological disorders which are  quite frequent in all age groups. They may range from very common condition like deficiency disorder to relatively rare multiple myeloma. The spectrum of hematological disorders is relatively different in the developing world than the developed countries. 
Commonly it is done for the evaluation of unexplained cytopenias and malignant conditions like leukemia. Bone marrow examination is also at times done for the diagnosis or staging of a neoplasm and storage disorders. Trephine biopsy is usually performed when there is hypoplasia or aplasia suspected on aspiration.
The present study was undertaken with the view to study the etiological spectrum of disorder as diagnosed on bone marrow examination and to know the age incidence and male to female ratio.
| Materials and Methods|| |
A retrospective and prospective study of patients who underwent bone marrow aspiration/biopsies was done during the period of one and a half year. Bone marrow was aspirated from sternum or posterior iliac spine after giving local anesthesia.
| Results|| |
Findings from a total 110 patients who underwent BMA/Trephine biopsy procedure were tabulated. [Table 1] and [Table 2] show the age and gender distributions of these patients, respectively. [Table 3] shows the bone marrow examination findings of study population. In the present study nutritional anemia contributed highest number of cases amongst the nonhematological group. Out of nutritional anemia; megaloblastic anemia was the most common disorder [Figure 1] a and b. Acute myeloid leukemia (AML) was the commonest malignant hematological disorder in the present study [Figure 2] a and b. Other malignant disorders include chronic myeloid leukemia, metastatic deposits primary from the prostatic carcinoma [Figure 3] a and b and multiple myeloma [Figure 4] a and b. Among 110 cases, 56 cases were male and 54 were female patients with highest number of cases in the age group of 21-30 years.

| Discussion|| |
The spectrum of hematological disorders both in children and adults is very wide. Bone marrow examination is a useful test in reaching the final diagnosis. Bone marrow trephine biopsy is an important adjunct to aspiration in arriving at an etiological diagnosis. BMA is one of the most common and safe procedure done routinely in medical practice. Rarely infection, excessive bleeding or embolism has been reported after bone marrow biopsy. 
In the present study we analyzed the data obtained from these patients to know the relative frequency of different hematological disorders.
In the present study nutritional anemia was the commonest disorder identified similar to a study by Rahim et al.  In other similar studies its frequency ranges from as low as 24% to as high as 68%. , Folate deficiency is more common in children, while B12 deficiency is more common in adults. 
The commonest hematological malignancy noted was AML similar to other studies such as Rahim et al. 
Lysosomal storage disorder is often diagnosed initially by bone marrow examination. 
One case of lysosomal storage disorder was diagnosed on bone marrow examination. We found that bone marrow examination is helpful in making primary diagnosis of storage disease either primary or secondary, in majority of pediatric cases.
Many studies have concluded that BMA will yield diagnostic result in majority of cases. , In our study also we could diagnose many cases on BMA alone.
Although BMA and biopsy is an uncomfortable procedure for the patient and should be performed only when there is a clear clinical indication,  yet it is a useful technique not only in the diagnosis of different blood disorders but also for various systemic illnesses including pyrexia of unknown origin.
