Malignant Transformation in Monostotic Fibrous Dysplasia
Malignant transformation in fibrous dysplasia (FD) is uncommon. The purpose of this study was to investigate clinical and imaging features, and outcomes of malignant transformation in monostotic FD. Data for 10 pathologically confirmed malignant transformations in monostotic FD from January 2005 to December 2013 were retrospectively reviewed. Patient data were recorded, and radiographs (n1⁄4 10...
متن کاملMalignant transformation of fibrous dysplasia: A case report
Secondary osteosarcoma from fibrous dysplasia (FD) is very rare. The etiology of FD is linked to activating missense mutations of the guanine nucleotide-binding protein α-subunit (GNAS) gene, which encodes the stimulatory α subunit of the G protein (Gsα) and is located at chromosome 20q13.

When the disease involves craniofacial skeleton, it results in significant disfigurement and other functional problems. This paper reports a case of large craniofacial fibrous dysplasia involving zygomaticomaxilla...
