Gnathic Osteosarcoma: Clinical, Radiologic, and Pathologic Review of Bone Beard Tumor
نویسندگان
چکیده
Gnathic (mandibular) osteosarcomas (OSs) account for approximately 6.5% of all OS, and most of them are secondary in nature, occurring in patients with Paget disease or fibrous dysplasia or as a late sequela to craniofacial radiotherapy. Primary OS of the jaw is rare and presents approximately two decades later than its appendicular counterpart; metastasis is uncommon with primary OS, and it has a better prognosis than appendicular OS. Radiologic depiction of a sunburst pattern of new bone formation is characteristic. Early diagnosis and complete tumor resection are mandatory to improve the prognosis of jaw OS.
