Introdução: As neoplasias mesodérmicas benignas que afetam a cavidade
oral constituem um grupo variado de lesões que se originam de diversos tecidos e
com diferentes prevalências. Embora apresentem uma variada histogénese, a sua
aparência clínica pode ser semelhante entre si, dificultando o seu diagnóstico.
Objetivo: O presente estudo pretende determinar a prevalência,
características clínicas e histológicas das neoplasias mesodérmicas benignas nos
pacientes da Clínica Dentária Universitária da Universidade Católica Portuguesa –
Viseu.
Materiais e Métodos: Para tal foi realizado um estudo retrospetivo
observacional descritivo de 20 anos, através da análise das seguintes variáveis:
género; idade; coloração; tipologia; localização; tamanho; técnica de biópsia; e
concordância entre diagnóstico clínico e anatomopatológico. Seguiu-se uma análise
estatística descritiva e inferencial com recurso ao software SPSS.
Resultados: Foram encontradas 31 neoplasias mesodérmicas, obtendo-se
uma prevalência de 16,5%. A média de idades foi 63,1 anos com prevalência do
género feminino (58%). A coloração mais comum das lesões foi normocolorado
(54,8%). Os tipos de neoplasias mais prevalentes foram o fibroma (77,4%), seguido
do hemangioma e fibrolipoma. As localizações anatómicas mais comuns foram a
mucosa jugal (33,3%) e a língua (29,6%). O diâmetro mais prevalente das lesões foi
o intervalo compreendido entre 0,5 cm e 1 cm (51,6%). As biópsias realizadas foram
na sua totalidade excisionais, e maioritariamente realizadas pelo método tradicional
- bisturi (54,8%). A concordância entre o diagnóstico clínico e anatomopatológico foi
de 87,1%.
Conclusões: Na população em estudo, as neoplasias mesodérmicas surgem
maioritariamente como crescimentos de pequenas dimensões, normocoloradas,
assintomáticas, na mucosa jugal, com predominância no género feminino e entre a
quarta e sexta décadas de vida. Uma correta caracterização e diferenciação entre
as diversas neoplasias mesodérmicas benignas fornece aos médicos dentistas o
conhecimento necessário para diagnosticar e tratar de forma adequada cada
paciente.
Introduction: Benign mesodermal neoplasms affect the oral cavity and constitute a varied group of lesions which could be originate from different tissues and present different prevalences. Although they present a varied histogenesis, their clinical appearance can be similar within the variety, making their diagnosis very difficult. Aim: Therefore, the aim of this study is to determine the prevalence, clinical and histological characteristics of benign mesodermal neoplasms of the Clínica Dentária Universitária, Universidade Católica Portuguesa – Viseu. Materials and Methods: 20-year retrospective descriptive observational study was perfomed, through the analysis of: gender; age; typology; lesion coloration; size; localization; biopsy technique; clinical diagnosis and histological characteristics of the lesion. This was followed by a descriptive and inferential statistical analysis using SPSS software. Results: 31 mesodermal neoplasms were included, with a prevalence of 16,5%. The mean age was 63,1 years with a female prevalence (58%). The most common lesions coloration was normocolored (54,8%). The most prevalent types of neoplasms were fibroma (77,4%), followed by hemangioma and fibrolipoma. The most common sites in which neoplasms develop were buccal mucosa (33,3%) and tongue (29,6%). The most prevalent diameter range size is about 0,5 – 1 cm (51,6%). The biopsies performed were entirely excisional, and mostly performed using the traditional method – scalpel (54,8%). The concordance between the clinical and anatomopathological diagnosis was 87.1%. Conclusions: The present study shows that mesodermal neoplasms usually tend to present a small growth, normocolored, asymptomatic, normally on the buccal mucosa, predominantly in females, aged between the fourth and sixth decades of life. A correct characterization and differentiation between the benign mesodermal neoplasms, in study, provides Dentists the knowledge to correctly diagnose, in order to manage the best treatment approach for each patient.
