Pathological study on some common bone tumors in human
The study aimed to find the most common bone tumors , affected ages and to identify gross and microscopical appearances
. Thirty bone tumor were obtained ; 28 cases diagnosed as primary bone tumor and 2 cases diagnosed as secondary bone
tumors . The primary benign bone tumors (13) while malignant bone tumor (11) and the rest (4) cases were tumor like conditions.
The primary bone tumors are diagnosed as follows osteoid osteosarcoma (4),osteoma(2),chondroblastoma(1),osteochondro
ma(6)chondrasarcoma (2), fibrosrcoma (1) , giant cell tumors (5) , hemangiosarcoma (1) , ewing sarcoma (1) , lymphoma (1)
. aneurysmal bone cysts (3) and fibrous dysplasia (1) . The secondary bone tumors (2) metastatic bronchial carcinoma case and
another case poorly differentiated prostatic carcimoma
Conclusion: Osteosarcoma is the most common malignant primary bone tumors and osteochondroma is the most common
benign primay bone tumor .
