RESUMEN
ABSTRACT An unusual case of intraosseous mucoepidermoid carcinoma is reported in a 22-year-old female, located in the posterior maxilla region. The article summarizes the main characteristics of the disease, including clinical-pathologic characteristics, treatment and prognosis.

RESUMEN
OBJECTIVE: The aim of this study was to investigate the frequency and some characteristics of odontogenic tumours, odontogenic cysts and non-odontogenic cysts in an elderly population (≥60 years). BACKGROUND: Few studies describe the distribution of oral lesions in older people. MATERIALS AND METHODS: A retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of four Brazilian referral centres between 2000 and 2016. Data such as gender, age, anatomical location, symptomatology and histopathological diagnosis were collected and categorised. Statistical analyses were performed adopting a P-value of ≤.05 and a 95% confidence interval. RESULTS: A total of 7259 biopsy records of elderly participants were analysed; 642 cases were cystic lesions and odontogenic tumours, 491 of which being classified as odontogenic cysts (76.5%), 75 as odontogenic tumours (11.7%) and 76 as non-odontogenic cysts (11.8%). The most frequent lesions in each group were radicular cyst (n = 268), ameloblastoma (n = 51) and salivary duct cyst (n = 21), respectively. Overall, women were more affected (n = 351, mean age: 68 years). Intraosseous lesions were more common in the mandible (n = 342), and soft tissue cysts occurred more in the lip (n = 13). CONCLUSION: Odontogenic cysts were relatively common, whereas odontogenic tumours and non-odontogenic cysts were rarer among the older people studied in the present investigation.

OBJECTIVES: To investigate the frequency of calcifying odontogenic cysts (COCs) that have been submitted for microscopic examination from representative geographic regions of Brazil and to compare it with literature data. MATERIALS AND METHODS: A retrospective study was conducted on biopsies obtained from 1953 to 2016 at 10 Brazilian oral and maxillofacial pathology centres. A total of 198,350 biopsy specimens were analysed. Demographic data and histopathological diagnosis were evaluated descriptively and statistically. In addition, a literature review of case series was carried out in four electronic databases. RESULTS: A total of 268 cases of COC were surveyed, representing 0.1% of the oral lesions at the centres studied. Female patients in their second decade of life and the maxilla were more affected. The mean lesion size of symptomatic individuals was larger than that of cases without symptoms (p = 0.026). The literature review showed a higher frequency in Asia and Europe, mainly affecting men in the third decade of life. CONCLUSIONS: COC is a rare lesion. Novel data on the clinicopathological features of 268 cases have been added to the literature. Data regarding gender and age of the Brazilian patients reported herein contrast with findings of case series and retrospective studies reported elsewhere.

OBJECTIVES: The aim of this study was to investigate the prevalence of oral and maxillofacial lesions among older adults (≥60 years) from representative regions in Brazil. DESIGN: Retrospective descriptive cross-sectional study. SETTING: Biopsy records were obtained from the archives of four Brazilian referral centers of oral diagnosis between 2000 and 2016. PARTICIPANTS: A total of 45,506 biopsy records of all patients were analyzed, of these 7,259 persons aged 60 and older were selected. MEASUREMENTS: Data such as gender, age, race, anatomical location, and histopathological diagnosis were collected and categorized. Pearson's chi-square test (P < .005) was used to evaluate differences in the frequency of the several groups of oral lesions. RESULTS: Oral and maxillofacial lesions were diagnosed in 7,259 older people, including 59.4% women (P < .001) and 61.3% white patients (P = .07). The most commonly affected sites were the cheek mucosa (20.3%) and mandible (8.9%) (P < .001). Reactive and inflammatory lesions were the most common lesions, followed by neoplasms. Oral squamous cell carcinoma was the most prevalent neoplasm (83.4%) (P < .001). CONCLUSION: Knowledge of oral diseases obtained from biopsy records provides more accurate data about the diagnosis and oral health of elderly patients. These indicators thus support the development of specific health policies for the prevention and treatment of oral and maxillofacial lesions that affect this population.
