Regarding the relation of the changes with the gender, age, DMFT index, and distribution by quadrants, did not show statistically significant differences (p > .05). Discussion and Conclusions: In this study, the prevalence of IA was higher than in other studies that revealed values of 0.3%, 0.5% and 0.27% [2-4], but close to Temilola et al. found 16.1% of cases of IA in a paediatric population in Nigeria [5]. There was no statistically significant relationship between DMFT and IA in the present study (p ! .05). Other studies have demonstrated a relationship between hyponeralization of the enamel and increased risk of caries [2,3]. The high prevalence of AI found in this study may be due to the fact that the majority of patients, with suspected rare alterations of the dental tissues, are frequently sent, to the consultation of the Egas Moniz Dental Clinic by family doctors, paediatrics and other dentists. When the dentist attends these cases, he must establish the diagnosis, inform the patient, and recommend the therapeutic approach that may have a multidisciplinary involvement.
Os tumores oncocíticos da supra-renal são neoplasias pouco frequentes. Atualmente existem 147 casos publicados. Os autores descrevem o caso de um homem de 34 anos admitido no hospital por lombalgias e febre. À observação identificava-se massa no quadrante superior esquerdo do abdomen. Os doseamentos das hormonas da supra-renal foram normais e a angiotomografia abdominal mostrou lesão retroperitoneal esquerda com 145 x 157 x 128 mm com extensas áreas necrosadas e hemorrágicas. O doente foi submetido a ressecção cirúrgica completa da lesão. O tumor pesava 1495 g e o exame anatomo-patológico concluiu tratar-se de tumor oncocítico da supra-renal com potencial maligno incerto. A maioria dos tumores oncocíticos é não funcionante e devem ser considerados no diagnóstico diferencial de tumores do córtex da supra-renal. O comportamento biológico e o seu prognóstico são variáveis e ainda estão mal estabelecidos. A propósito da raridade deste tipo de tumores os autores fazem uma revisão da bibliografia publicada.
