Osteosarcoma of the bone: clinico-pathologic features of sixty-nine cases in Ibadan, Nigeria

Sixty-nine patients with primary osteosarcoma of the bone are reviewed. There were 50 males and 19 female; a male predominance of 2.6:1. The patients presented in advanced stages. In agreement with other authors, we found a peak incidence in the second decade. No associated Paget's disease was found in any of the elderly patients. The long bones of the lower limbs were the most frequently affected. Treatment with amputation was not acceptable to the great majority of our patients.
