Cisto glandular odontogênico: uma lesão incomum que requer tratamento agressivo / Glandular odontogenic cyst: an uncommon lesion that requires aggressive treatment

O cisto glandular odontogênico (CGO) é uma rara lesão, descrita em 1988. Seu tratamento preferencialmente consiste em cirurgia radical, com ressecção em bloco, seguido de reconstrução. Os autores relatam um caso em paciente masculino, 59 anos, que procurou atendimento odontológico com queixa de aumento de volume em mandíbula. Realizou-se exame radiográfico panorâmico, que mostrou lesão cística em região anterior de mandíbula. Foi realizada biópsia, cujo diagnóstico foi cisto odontogênico não classificado. O paciente foi submetido à curetagem intra-lesional e o exame anatomo-patológico definitivo mostrou ser CGO. Com base nesse resultado, optou-se pela ampliação de margens com ressecção em bloco da lesão, seguida de reconstrução primária. O paciente encontra-se bem com seguimento de seis meses.

The glandular odontogenic cyst (GOC) is a rare lesion, first described in 1988. Radical surgery is the first choice of treatment through an en-bloc resection and reconstruction. The authors report a case in a 59 years old male patient that was referred to the oral surgeon for evaluation of localized mandible enlargement. The oral surgeon obtained a panoramic radiography that showed a cystic lesion in anterior region of mandible. The patient underwent mandible cyst biopsy witch reveals an odontogenic cyst with no classification. He underwent intralesional curettage and the final pathology diagnosis was GOC. In base of these results, the oral surgeon opted to perform a radical en-bloc resection followed by primary reconstruction. Nowadays, the patient is asymptomatic and his clinical examination was unremarkable. He has a six month period of follow-up with no evidence of disease.

Osteogenic sarcoma of the maxilla: case report

Osteosarcoma (OS) is one of the most common primary malignant bone neoplasms, which predominantly occurs in the long bones and rarely in the maxillofacial area. We present a rare case of maxillary OS early diagnosed in a 17-year-old girl through clinical, radiological and histological examination. The treatment involved surgical resection of the tumor followed by radiation therapy and chemotherapy. The patient was much younger than the average age of presentation of a jaw tumor, which typically presents in the third to fourth decades of life. Although there is a consensus in the literature that OS of the jaws is less aggressive and less prone to metastasis than OS of the long bones, that was not true in this case, where in spite of early diagnosis and treatment the patient died due to brain metastasis.
