There was no history of endocrine disturbances and no previous irradiation. Malignant transformation in fibrous dysplasia is rare. A review of the literature reveals 101 cases of malignant degeneration occurring in fibrous dysplasia. We believe that this is the first report of sarcomatous change arising in an area of fibrous dysplasia in the spine. © 1995 Springer-Verlag.en10.1007/BF00300303info:eu-repo/semantics/closedAccessFibrosarcoma; Fibrous Dysplasia; Malignant TransformationAdult; Article; Case Report; Fibrosarcoma; Fibrous Dysplasia; Human; Human Tissue; Male; Priority Journal; Spine Cancer; Case Report; Cell Transformation, Neoplastic; Fibrosarcoma; Fibrous Dysplasia Of Bone; Human; Male; Middle Age; Spinal Diseases; Spinal NeoplasmsArticle463723742-s2.0-00288648418983661Q1
