Intraoral Pleomorphic Adenoma in Young Patients.

BACKGROUND: Intraoral pleomorphic adenoma (PA) is rare in young individuals, with only single clinical reports or small patient series reported previously. AIM: The aim of this study was to describe the clinicopathological features of PA in 4 patients under 18 years of age, and to discuss the differential diagnosis of pediatric patients presenting with intraoral submucosal nodules. METHODS: Between 2000 and 2015, all patients of intraoral PA in patients aged ≤18 years diagnosed in the Oral Pathology Laboratory of the Universidade Federal de Pernambuco, Brazil, were retrieved for the study. Clinical data were recorded from the clinical charts. Histopathological slides stained with hematoxylin and eosin were reviewed to confirm the diagnosis. RESULTS: There were 4 cases of PA in patients aged ≤18 years. All patients in this patient series were males, with a mean age of 16.7 years. Three cases occurred in the palate, and in 1 case, the upper lip was affected. All PAs appeared as a painless, smooth surface, well-circumscribed, and submucosal nodule. All patients were surgically excised and subsequent histopathological analysis revealed well-circumscribed tumors composed of cells that were arranged in ducts within a fibromyxoid stroma. No signs of recurrence were observed in 3 patients after a mean follow-up of 30 months. One patient is lost to follow-up. CONCLUSION: Although PAs are unusual in young patients, they should be considered in the differential diagnosis of oral submucosal nodules.

Lesão de tecido mole em pacientes vítimas de trauma buco-maxilo-facial / Soft tissue injury in victims of bucco-maxillo-facial trauma

Objetivo: este artigo teve como objetivo avaliar a prevalência e o perfil de lesões de tecido mole na face de pacientes atendidos no Hospital da Restauração- HR, no período de setembro/2011 - julho/2012. Metodologia: Para compor a amostra, foram selecionados 160 pacientes, tendo os dados sido obtidos com base em questionário, referentes aos dados pessoais e às circunstâncias do trauma. a outra parte da coleta de dados aconteceu por meio do exame físico para se verificar a presença das lesões nos tecidos moles faciais, sendo sua localização e aspecto registrados e documentados. Resultado: Os traumatismos faciais ocorreram, preferencialmente, em homem (81,9%) na fase adulto jovem (34,4%), sendo a maioria decorrente de acidente automobilístico (46,2%) e violência interpessoal (22,5%). Os locais anatômicos mais comuns foram a região frontal (43,8%) e os lábios superior e inferior (20,6%). O tamanho das lesões em tecido mole variaram em 58,6% dos pacientes que apresentaram lesão de 1,01- 5cm, 31,7% de 0,01- 1 cm. Conclusão: Neste estudo, verificou-se que as lesões de tecido mole acometem, principalmente, homens em decorrência de acidentes de trânsito, sendo essas lesões variáveis de 0,2 cm a 10 cm de tamanho, com predominância de uma lesão por paciente. verificou-se, ainda, que a região mais acometida foi a frontal.

Object: This paper set out to evaluate the prevalence and components of facial soft tissue injuries in patients treated at Hospital da Restauração - HR from September 2011 to July 2012. Method: The sample comprised 160 patients, who were interviewed using a questionnaire to obtain data on their personal particulars, time and location of the trauma event, use of safety devices, driver's license and alcoholic beverage intake. Result: Facial trauma occurred mainly in men (81.9%), 34.4% of whom were young adults. Most of facial traumas were due to a motor vehicle accident (46.2%) and interpersonal violence (22.5%). The most common anatomical locations of the injuries were the frontal region (43.8%) and the upper and lower lips (20.6%). The size of the lesion ranged from 0.2 to 24 cm, with 58.6% of patients having injuries ranging from 1.01 to 5 cm and 31.7% with injuries from 0.01 to 1 cm. Conclusion: Facial soft tissue injuries occur mainly in men and are due mostly to motor vehicle accidents. The injuries ranged from 0.2 to 10 cm, with an average occurrence of one injury per case, the frontal region being the most affected.
