RESUMEN
OBJECTIVES: The aim of this study was to investigate the prevalence of oral sarcomas from geographic regions of Brazil. MATERIALS AND METHODS: A cross-sectional study was conducted on biopsies obtained from January 2007 to December 2016 at twelve Brazilian oral and maxillofacial pathology centres. Gender, age, evolution time, clinical aspects, tumour location, tumour size at diagnosis, radiographic aspects and histopathological diagnosis were evaluated. Data were analysed using descriptive statistical methods. RESULTS: From 176,537, a total of 200 (0.11%) oral sarcomas were reported, and the most prevalent were osteosarcomas (74 cases; 37%) and Kaposi's sarcomas (52 cases; 26%). Males were more affected than females at a mean age of 32.2 years old (range of 3-87 years). The most common symptoms were swelling¸ localised pain and bleeding at a mean evolution time of 5.14 months (range <1-156 months). The lesions were mostly observed in the mandible (90 cases; 45%), with a mean tumour size of 3.4 cm (range of 0.3-15 cm). Radiographically, the lesions presented a radiolucent aspect showing cortical bone destruction and ill-defined limits. CONCLUSIONS: Oral sarcomas are rare lesions with more than 50 described subtypes. Osteosarcomas and Kaposi's sarcomas were the main sarcomas of the oral cavity in Brazil.

OBJECTIVE: To integrate the available data published on central mucoepidermoid carcinoma (CMC) into a comprehensive analysis of its clinical aspects, histology, treatment, and prognostic factors. METHODS: An electronic search was undertaken in July 2017. Eligibility criteria for publications included having clinical, histological, treatment, and time of follow-up data to confirm the diagnosis. RESULTS: In addition, gender, histological grade, conservative treatment, and lymph node metastasis were significant independent prognostic factors. CONCLUSION: Male patients with histological grade III CMC of the jaw bone, who used conservative treatment as the main treatment, and presented with lymph node metastasis, were more likely to have a worse prognosis.
