ABSTRACT

A avaliação clínica nem sempre é suficiente para garaA avaliação clínica nem sempre é suficiente para garantir o diagnóstico das lesões orais. O objetivo deste artigo é avaliar a validade do teste com o azul de toluidina como método auxiliar no diagnóstico de lesões orais. A amostra constituiu-se de 110 pacientes com lesões orais. Seguindo o protocolo estabelecido para este trabalho, todas as lesões foram submetidas ao teste do azul de toluidina. Um total de 105 lesões foram biopsiadas e a histopatologia considerada padrão-ouro diagnóstico. O teste do azul de toluidina foi positivo em 31 das 110 lesões, com 20 marcações focais e 11 difusas. Concluiu-se que, o teste do azul de toluidina é um recurso útil como método auxiliar no diagnóstico de lesões orais.

ABSTRACT

OBJECTIVE: To compare the findings of the clinical examination of the oral cavity with and without theaid of an intraoral video camera (“videoroscopy”) with the purpose of diagnosing epithelial precursorlesions (leukoplakia, erythroplakia and actinic cheilitis) and precancerous conditions (lichen planus).MATERIALS AND METHODS: Both forms of examination were performed in 100 patients withincreased risk of oral cancer. All patients were examined without the aid of any enlargement apparatusbefore the intraoral video camera was used. After each of the exams, the presence or absence of epithelialprecursor lesions or lichen planus was recorded. In the event a lesion was found, a digital picture was takena toluidine blue staining test was performed and then a biopsy was done. RESULTS: Of the patients withepithelial precursor lesions or lichen planus, 80% of the lesions had been observed in both of the examinationswhile 7% only had been diagnosed the after the videoroscopy. The results of the histopathological analysisand the toluidine blue staining tests are also presented. CONCLUSIONS: In this study videoroscopy issuggested for use on a regular basis in patients with an increased risk of oral cancer in an attempt to diagnoseearly lesions, select of the best area to be biopsied and during the following up of these lesions.


OBJETIVO: Comparar os achados do exame clínico da boca com e sem auxílio da vídeo-câmeraintrabucal (videoroscopia) com o propósito de diagnosticar lesões epiteliais precursoras(leucoplasia, eritroplasia, eritroleucoplasia e queilite actínica) e condições pré-cancerosas (líquen plano). MATERIAL E MÉTODOS: Os exames foram realizados em 100 pacientes com riscoaumentado para câncer oral. Todos os pacientes foram examinados sem o auxílio de qualqueraparelho de aumento antes que a vídeo-câmera intrabucal fosse usada. Após cada exame, a presençaou ausência de lesões epiteliais precursoras ou líquen plano foram anotadas. Nos casos em quelesões foram diagnosticadas, fotografaram-se as lesões, bem como o teste do azul de toluidina ea biópsia. RESULTADOS: Dos pacientes com lesão epitelial precursora ou líquen plano, 80%das lesões foram observadas em ambos os exames, enquanto 7% foram somente diagnosticadasapós a videoroscopia. Os resultados histopatológicos e dos testes com azul de toluidina foramtambém discutidos. CONCLUSÕES: Sugere-se a utilização regular da videoroscopia nos pacientescom risco aumentado para o câncer de boca, para auxiliar o diagnóstico de lesões precoces, naseleção da melhor área para a biópsia e acompanhamento dessas lesões.

ABSTRACT

A avaliação clínica nem sempre é suficiente para garantir o diagnóstico da lesão. O objetivo deste estudo foi avaliar a utilização da vídeo-câmera oral no diagnóstico de lesões. A amostra constituiu-se de 180 pacientes; 105 lesões identificadas foram documentadas e submetidas à biópsia. As lesões biopsiadas foram agrupadas e o padrão-ouro foi a histopatologia. Houve concordância de 89% entre o diagnóstico histopatológico e videoroscopia auxiliada pela oroscopia. Foi concluído que a videoroscopia auxilia a visualização das lesões orais principalmente em locais de difícil acesso, em lesões incipientes, com pouca espessura e/ou de pequeno tamanho.

ABSTRACT

Oral squamous cell carcinoma represents approximately 90% of all oral malignancies and in some cases can be preceded by lesions considered epithelial precursor lesions. Early diagnosis of these lesions and intervention at an early stage constitute keys to reduce mortality, morbity and expenses with oral cancer treatment. The objective of this paper is to present the prevalence of epithelial precursor lesions and oral squamous cell carcinoma at the Anatomic Pathology Service of Antônio Pedro University Hospital, Fluminense Federal University in the last ten years. Considered data were sex, age, race, location, addictions, clinical and histological aspects. A total of 3,752 oral lesions were found and evaluated. The epithelial precursor lesions represented 4.23% of the oral biopsies, while the squamous cell carcinoma represented 4.21%. Leukoplakia was the most prevalent clinical aspect among the epithelial precursor lesions. The white women in their sixties were the mostaffected and the buccal mucosa was the most common anatomic localization. The most frequent histological finding was the epithelial hyperplasia without dysplasia. The squamous cell carcinoma showed up clinically as an ulceration in 80.3% of the cases. The white men in their sixties were the most affected. The tongue was the most affected area. In relation to the histological classification, the most frequent type was the moderately differentiated squamous cell carcinoma. The patientswith epithelial precursor lesions and with squamous cell carcinoma were smokers in its majority.
