Oral Langerhans Cell Histiocytosis in Two Pediatric Patients.

We report two cases of Langerhans cell histiocytosis (LCH) in the oral cavity of children. An 11-month-old girl was referred for evaluation of a nodular and sessile lesion in the alveolar ridge covering the primary left mandibular central incisor. The second patient was a seven-year-old boy with an ulcerated lesion in the gingiva covered by necrotic areas, extending to the sulcus of the vestibule. The patients underwent incisional biopsies and histopathological exams showed a proliferation of Langerhans and eosinophil cells, suggesting a diagnosis of LCH, which was confirmed by positive immunohistochemical expression of S100 and CD1.

Successful hair removal on intraoral grafts using the diode laser: Report of two cases.

AIM: The aim of this study was to describe the successful epilation of intraoral grafts using the diode laser system. METHODS AND RESULTS: Two male patients at a 12-month follow-up - who underwent radical resection of oral cancer located in the mouth floor and tongue followed by reconstruction with cutaneous flap - showed hypertrichosis in the graft region, leading to dysphagia and dysphonia. The diode (980 nm) laser was performed for both cases in order to remove the ectopic hair. Excellent aesthetic and functional outcomes with total hair removal and alteration of the tissue surface were achieved. CONCLUSIONS: There is no currently standard protocol for the laser epilation use on hairy grafts because each graft required a different number of sessions for total epilation. The diode laser system appears to be a successful therapeutic option for patients suffering from hypertrichrosis in the oral cavity.

Prevalência e caracterização das lesões orais na Clínica de Estomatologia da Policlínica Piquet Carneiro ­ Estudo Retrospectivo de 12 anos / Prevalence and characterization of oral lesions in the Stomatology Clinics of the Piquet Carneiro Polyclinics 12-Year Retrospective Study

Objetivo: avaliar a prevalência dos principais tipos de lesões submetidas à biópsia e identificar o perfil dos pacientes atendidos no ambulatório de Estomatologia da Policlínica Piquet Carneiro (PPC/UERJ, Rio de Janeiro) no período compreendido entre 2000 e 2012. Material e Métodos: estudo transversal e retrospectivo em que prontuários de 2078 pacientes foram avaliados e dados referentes às doenças, idade, gênero, cor da pele e localização anatômica das lesões foram coletados e analisados de forma descritiva. Resultados: 69% dos pacientes (1441 casos) obtiveram o diagnóstico conclusivo através de exame histopatológico, ao passo que 31% (637 casos) obtiveram um laudo histopatológico descritivo. Dos casos com diagnóstico histopatológico conclusivo, 58% eram mulheres, 31% homens e em 11% o sexo não foi informado. A média de idade da população estudada foi de 50,63 anos e em 58% dos casos os pacientes eram leucodermas. O maior número de lesões foram as do grupo dos processos proliferativos não-neoplásicos, sendo a hiperplasia fibrosa inflamatória (30,1%) a mais prevalente. Conclusão: o perfil epidemiológico do paciente atendido no período estudado foi composto predominantemente por mulheres com mais de 50 anos de idade e a lesão oral mais prevalente foi a hiperplasia fibrosa inflamatória. Este estudo reforça a importância do papel da análise histopatológica como método auxiliar de diagnóstico e que possibilita a elaboração de estratégias específicas para prevenção e detecção precoce das doenças orais mais frequentes na população

Objective: to evaluate the prevalence of the main types of lesions submitted to biopsy and to identify the profile of patients attended at the Stomatology Clinics of the Piquet Carneiro Polyclinics (PPC/UERJ, Rio de Janeiro) between 2000 and 2012. Material and methods: this is a cross-sectional and retrospective study in which medical records of 2,078 patients were evaluated and data referring to diseases, age, sex, skin color and anatomical location of the lesions were collected and analyzed descriptively. Results: A total of 69% of patients (1,441 cases) obtained the conclusive diagnosis by histopathological examination, whereas 31% (637 cases) obtained a descriptive histopathologic report. Of the cases with conclusive histopathological diagnosis, 58% were women, 31% were men and 11% did not inform their sex. The mean age of the studied population was 50.63 years and in 58% of the cases the patients had light skin. The largest number of lesions were from non-neoplastic proliferative processes, and the inflammatory fibrous hyperplasia (30.1%) was the most prevalent. Conclusion: the epidemiologic profile of patients attended during the study period consisted predominantly of women over 50 years of age and the most prevalent oral injury was inflammatory fibrous hyperplasia. This study reinforces the importance of the histopathological analysis as a diagnostic auxiliary method that enables the elaboration of specific strategies for prevention and early detection of the most frequent oral diseases in the population
