ABSTRACT

The authors studied seven patients with gingival carcinoma attended at the Head and Neck Surgery and Otorrhinolaryngology Service and the Diagnostic Imaging Service of "Complexo Hospitalar Heliópolis", São Paulo, SP, Brazil, between 1985 and 1996. Squamous cell type carcinomas were identified in all cases. All patients were male (100%) aged 48-72 years. Computed tomography was performed in six patients (85.6%). Four patients (57.1%) had not received any treatment before imaging examination whereas three patients (42.8%) had already been submitted to surgery or radiotherapy. The authors analyzed the primary site of the tumor and its extension to the mandible (5/7 cases; 71.4%), the floor of the mouth (3/7 cases; 42.8%), the floor of the maxillary sinus (1/7 cases; 14.2%) and the retromolar trigonum (1/7 cases; 14.2%). Metastatic lymph nodes were observed in five patients (71.4%). Diagnosis was confirmed by biopsy and histopathological examination in all cases. Comparison with surgical findings was possible in five cases (71.4%).

RESUMO

Os autores estudaram sete casos de carcinoma de gengiva atendidos no Serviço de Cirurgia de Cabeça e Pescoço e Otorrinolaringologia e no Serviço de Diagnóstico por Imagem do Complexo Hospitalar Heliópolis, São Paulo, SP, entre 1985 e 1996. Todos os casos eram carcinomas do tipo espinocelular. Os sete pacientes eram do sexo masculino (100%), com idade variando entre 48 e 72 anos (média de 57 anos). Exame de tomografia computadorizada foi realizado em seis (85,6%) dos sete pacientes. Quatro pacientes (57,1%) eram não tratados na ocasião do exame de imagem e três pacientes (42,8%) já tinham tido algum tipo de tratamento (cirurgia ou radioterapia). Além disso, os autores analisaram o local primário e as extensões locais para a mandíbula (5/7 casos; 71,4%), para o soalho da boca (3/7 casos; 42,8%), para o soalho do seio maxilar (1/7 casos; 14,2%) e para o trígono retromolar (1/7 casos; 14,2%). Linfonodos metastáticos foram observados em cinco pacientes (71,4%). Biópsia e exame histopatológico confirmaram todos os casos. Confrontação com achados cirúrgicos foi possível em cinco casos (71,4%).
