Abstract
Myositis ossificans is a benign lesion characterized by focal heterotopic soft tissue ossification and occurring in young people generally after localized trauma. It can mimic osteosarcoma but it rarely degenerates. We report a case of a patient with myositis ossificans which degenerates into extra-skeletal osteosarcoma.
