Introduction: Bone sarcomas account for 0.2% of all malignancies. Many relevant demographic, clinical and epidemiological characteristics have been reported.

Objectives: To analyze the spectrum of primary bone tumors and their relative frequency in Gandhi Medical College and Hamidia Hospital, Bhopal.

Methods: This is a three and a half year study conducted from July 2012 to December 2015. All primary bone tumors confirmed by histopathology have been included.

Results: A total of 124 cases of primary bone tumours were studied. Age range varied from 7 to 92 years with a mean age of 24.4 years. Among these, 55.65% were males and 44.35% were females. On histological examination, 51.6% were benign and 48.4% cases were malignant. Giant cell tumor was the commonest benign tumor (39.7%) and osteosarcoma was the commonest malignant tumor (56.7%). Maximum number of cases belonged to the 2^nd decade followed by 3^rd and 4^th decade. Clinically, all patients presented with swelling, hence the most common symptom. 42% patients presented with both pain and swelling.

Conclusion: The pattern and distribution of bone tumors seen at our centre are similar to those reported from other studies. Males were more commonly affected than females with a peak in the second decade of life. Long bones of lower extremity were the most commonly affected sites. Giant cell tumour and osteosarcoma were the commonest benign and malignant varieties respectively.
