ALVAREZ MARTINEZ, E.; CASTRO ESPITIA, L. e ARDILA MEDINA, C.M.. Chondroblastic osteosarcoma of the maxilla: A case report. Av Odontoestomatol [online]. 2012, vol.28, n.5, pp.227-231. ISSN 2340-3152.
Osteosarcomas are neoplasms characterized by the presence of mesenchymal cells that produce osteoid. The clinical manifestations in the oral cavity include pain, swelling, teeth displacement, twitching, paresthesia, and nasal obstruction. This paper presents an advanced chondroblastic osteosarcoma in the maxilla. Histological examination showed extensive cartilaginous neoplastic proliferation, with small areas in which osteoid formation was identified and non-lamellar bone, surrounded by neoplastic cells. The treatment consisted in maxillectomy and bilateral neck dissection. In addition, sealing stents were placed to seal the defect orosinonasal communication. Although osteosarcoma of the jaw has a better prognosis than osteosarcoma of long bones, jaw osteosarcoma patients with advanced tumors can occur, especially when the proper diagnosis is not appropriate.
