HISTOPATHOLOGICAL STUDY OF BONE LESIONS AT DARBHANGA MEDICAL COLLEGE, LAHERIASARAI, BIHAR.
Background: A spectrum of pathological bone lesions can be presented in any form from inflammatory to neoplastic conditions. Diagnosis of all bone lesions is made by radiological modalities like plain X-ray, CT scan, MRI and bone scintigraphy. Aim and Objectives: To study histopathological features of bone lesions and correlate them with age, site and type of lesions. Material and Methods: The study was carried out at Department of Pathology associated with Orthopaedics, Darbhanga Medical College, Lahertiasarai, Bihar from April 2020 to November 2020. A total of 102 bone lesions were analyzed. Bone biopsy was performed after detailed clinical and radiological examination. After fixation, decalcification, processing and H&E staining, histopathological diagnosis was made. Results: Out of all 102 cases, 44.11% bone lesions were found between 25-50 years with male predominance. The incidence of non neoplastic lesions was 74.5% and neoplastic lesions were 25.4%. Amongst neoplastic lesions, incidence of benign tumors was 17.64% and malignant tumors were 7.8%. The Tuberculous Osteomyelitis was most common non neoplstic lesion while giant cell tumor and osteochondroma were common among benign tumors and osteosarcoma and Secondary metastasis were common among malignant bone tumors. Conclusion: Though Bone tumors are less common, if viewed in perspective of clinico radiology and histopathology, correct diagnosis can be made.
