“…It can also be seen in preexisting Paget's disease of bone and fibrous dysplasia. In the maxillomandibular region, most osteosarcoma have an osteoblastic nature, with deposition of a variable amount of osteoid matrix with minimal cytological atypia and usually with undifferentiated lesions [6,9]. In our case histological tumor was typical of the chondroblastic type.…”

“…In the maxillomandibular region, most osteosarcomas have an osteoblastic nature, with deposition of a variable amount of osteoid matrix, with minimal cytological atypia and usually with well-differentiated lesions 4,5 . In our case, histologically the tumor was composed of cells with shapes varying between oval and spindle-like with mild cellular pleomorphism, responsible for the deposition of extensive osteoid areas, typical of the osteoblastic type (Figures 2 and 3).…”

O osteossarcoma é um tumor mesenquimal maligno, no qual as células cancerosas produzem matriz óssea. É o tumor maligno primário mais comum do osso, responsável por aproximadamente 20% dos sarcomas, sendo que 5% destes ocorrem nos maxilares. Possuem variados aspectos não só clínicos e histopatológicos como também no curso e prognóstico. Este artigo apresenta um relato de caso de paciente do sexo feminino, com 20 anos de idade, que nos foi encaminhada apresentando aumento de volume na região de pré-molar inferior esquerdo. Após diagnóstico clínico de lesão do periápice dental, a paciente foi submetida previamente a tratamento endodôntico do dente envolvido, a partir do qual, em um período de 11 dias, pode-se observar um considerável aumento da lesão provocando visível assimetria facial. A radiografia oclusal mostrava imagem compatível com área de destruição óssea e formação de osso anormal na região, com cortical externa exibindo evidente radiopacidade semelhante a raios de sol, sugerindo o diagnóstico de osteossarcoma. A lesão foi biopsiada e obteve-se o diagnóstico histopatológico de osteossarcoma. A paciente foi então submetida à mandibulectomia parcial e uma reconstrução da área, usando osso de costela e enxerto de pele da nádega, para o revestimento da mucosa oral envolvida. Aos 8 meses após a cirurgia houve recorrência local da lesão e a paciente foi a óbito aproximadamente 1 ano depois da recidiva.

Abstract:Osteosarcoma is a malignant mesenchymal tumor whose cancerous cells produce osteoid matrix. It is the most common primary malignant bone tumor, accounting for approximately 20% of the sarcomas, but osteosarcoma of mandible is rare only 5% of the osteosarcomas occur in the jaws and occur mainly in adult population in their later part of the life. They present various clinical and histological aspects, as well as variable disease progression and outcome. Mandibular osteosarcoma are slow growing tumors and have better prognosis compared to other site. Lung is the most common site of metastasis in osteosarcoma mainly in the long bones, in craniofascial osteosarcoma lung metastasis is a rare findings. We are presenting a case of osteosarcoma of mandible in 5 year child with aggressive initial presentation. Keywords: Aggressive Mandibular Osteosarcoma, Lung MetastasisOsteosarcoma(OS) is the most common primary malignant bone neoplasm, predominantly occurring in long bones and occasionally in the maxillofacial area. Accounts 5-9% of OS, Maxilla and the mandible are the most involved site.1-4 Mandibular osteosarcoma is often considered a distinct entity because of its predilection to older patients (mean age: 34 to 36 years). In addition, metastases are rare and the prognosis is significantly better and rarely develops distant metastases, when compared to its counterpart in long bones.3-8 we are presenting a case of 5 year old male child a case of osteosarcoma of mandible with lung metastasis.
