Secondary osteosarocma is a rare but serious complication of paget’s disease and paget’s osteosarcoma mainly affect elderly population. Most recent study by Mirabello et al11 shows that age-adjusted incidence rates in 0-24 years age group is 4.4 per million, which represents approximately 53% of all reported osteosarcoma cases with only 1 case of Paget’s osteosarcoma in this age group.
Individuals ages 25 to 59 years had the lowest incidence rates of osteosarcoma (1.7 per million) that (...)

GNAS-based heterotopic ossification
18 June 2008Types
progressive osseous heteroplasia (POH) Progressive osseous heteroplasia (POH) is a rare autosomal dominant disorder characterized by dermal ossification beginning in infancy, followed by increasing and extensive bone formation in deep muscle and fascia. Progressive osseous heteroplasia (POH) is caused by paternally inherited inactivating mutations of the GNAS1 gene (MIM.139320).

spondyloepiphyseal dysplasias
11 February 2008Spondyloepiphyseal, metaphyseal and spondylometaphyseal dysplasias are a group of hereditary skeletal diseases, which lead to small stature, axial deformities of the lower extremities and spinal deformities. They differ in pathophysiology, heredity and in their clinical and radiologic appearance.
