RESUMO
Ameloblastoma is a slow-growing benign neoplasm that has a strong tendency to local invasion and that can grow to be quite large without metastasizing. Rare examples of distant metastasis of an ameloblastoma in lungs or regional lymph nodes do exist. It has an aggressive and recurrent course and is rarely metastatic. Radiographically it shares common features with other lesions such as the giant cell tumor, aneurysmal bone cyst, and renal cell carcinoma metastasis; a definitive diagnosis can only be made with histopathology. Basal cell ameloblastoma is believed to be the rarest histologic subtype in which the tumor is composed of more primitive cells and has even fewer features of peripheral palisading. Till date, only few cases of basal cell ameloblastoma have been reported in the literature. Considering the rarity of the lesion, we report here an interesting and unique case of basal cell ameloblastoma of the mandible occurring in a very old patient.
RESUMO
Osteomas of the facial bones are a rare entity and very few cases have been reported in the literature. Osteomas are benign neoplasms, often asymptomatic and consist of well-differentiated matured bone. There are three varieties of osteomas- the central type arising from the endosteum, the peripheral type arising from the periosteum, and the extra-skeletal soft tissue osteomas which usually develops within the muscle. In the facial bones, both central and peripheral osteomas have been described. Peripheral osteomas have been described to occur in the frontal, ethmoid, and maxillary sinuses, but are not common in jawbones. We describe a rare case of symptomatic peripheral osteoma of mandible in a middle-aged female patient.
RESUMO
OBJECTIVE: To review the literature and present a case of Gorlin´s syndrome with situs inversus. RESULTS AND DISCUSSION: Together with the major features, a great number of processes considered as minor features have also been described in the Gorlin´s syndrome. The latter includes numerous skeletal, dermatology related and neurological anomalies among others. In the present clinical case many criteria allowed a diagnosis of Gorlin´s syndrome, but for the first time this unique finding of situs inversus is seen with this syndrome. CONCLUSION: However, further research is needed to confirm the association between situs inversus and Gorlin´s syndrome.
OBJETIVO: Revisar a literatura e apresentar um caso de síndrome de Gorlin com situs inversus. RESULTADOS E DISCUSSÃO: Conjuntamente com os aspectos principais, um grande número de processos considerados menores têm sido descritos na síndrome de Gorlin. Entre outras, numerosas anomalias esqueletais, dermatológicas e neurológicas têm sido relatadas. No presente caso clínico, muitos critérios permitiram o diagnóstico da síndrome de Gorlin, porém, pela primeira vez relata-se a ocorrência deste achado único, o situs inversus. CONCLUSÃO: Entretanto, pesquisas adicionais são necessárias para confirmar a associação entre situs inversus e síndrome de Gorlin.
