title: Osteosarcoma of the scapula arising in osteogenesis imperfecta.
abstract: A case of osteosarcoma arising in the scapula of a 37 year old woman with severe congenital sporadic white sclera type osteogenesis imperfecta (OI) is presented. Osteosarcoma occurs as a sporadic rather than a related occurrence in patients with OI. A delay in the diagnosis of osteosarcoma may occur due to the similarity in symptomatology between the two conditions and because of the difficulty in differentiating between hyperplastic callus and tumor using conventional radiographic imaging techniques.
