Abstract

Background: Bone tumours are comparatively uncommon among wide array of lesions and pose a diagnostic problem as they constitute a small portion of diagnostic experience among pathologist. Aims &
Objective: To study the histopathological features of bone lesions and their correlation with age of presentation, site and type of lesion. Material and Methods: The present study was carried out at a tertiary care center from October 2003 to January 2006. A total of 79 bone lesions were analyzed. A detail clinical and radiological history was taken. Bone biopsy was performed by either percutaneous method with needle/drill or Open surgical biopsy. If attached soft tissue was also received, bony tissues were put for decalcification (10% nitric acid) and soft tissue was immediately fixed into 10 % formalin and processed by paraffin embedding. Sections were stained by haematoxylin and eosin stain.
Results: Incidence of non-neoplatic and benign neoplastic lesions was 68.40% while that of malignant lesion was only 20.22%.Younger patients (58.24%) and males (59.49%) were more commonly affected. Amongst non-neoplastic lesions, tuberculous lesions (17.72%) were commonest while exostosis (15.19%) and osteosarcoma and chondrosarcoma were common benign and malignant neoplastic lesions respectively. Overall most common bone involved was femur. In tuberculous lesions, vertebrae were commonly involved. Osteolytic lesions were more common. Metaphysis was the commonest site. Conclusion: Though bone tumours are less common lesions and pose a diagnostic problem, if viewed in perspective of clinico-radiology and histopathology, a correct diagnosis can be reached.
