RESUMEN
CONTEXT: Paranasal sinus cancer is considered rare, with an incidence of less than 1 per 100,000 per year, with the frontal sinus being the primary site in only 0.3 per cent. We report a case of adenocarcinoma arising in the frontal sinus. DESIGN: Case report. CASE REPORT: A 59-year-old woman, secretary, came in February 1998 with a 4-month history of low intensity frontal headache. She denied contact with wood dust. On examination a non-tender swelling was noted over her right forehead next to the medial aspect of the right orbit. CT scan showed a soft-tissue mass involving frontal sinus with intracranial invasion through the posterior wall. The anterior ethmoid sinus and the medial aspect of the right orbit were also involved. MRI demonstrated dural thickening in communication with the frontal mass. She underwent an en-bloc tumor resection by craniotomy including orbital clearance. Histology revealed an adenocarcinoma. After surgery she had tumor recurrence, and chemotherapy and radiotherapy were started resulting in partial improvement

Foi realizada gastrectomia subtotal paliativa, pois encontrou-se linfonodos para-aorticos comprometidos pela neoplasia, confirmado pelo exame anatomo-patologico de congelacao realizado no decorrer da intervencao. Ao fim da confeccao da gastroentero-anastomose o paciente passou a apresentar bradicardia intensa: 38 batimentos por minuto (bpm), hipotensao arterial, alteracoes do tracado do eletrocardiograma (Supra-desnivelamento do segmento ST) e parada cardiaca. Realizadas as manobras de ressucitacao com sucesso temporario, ja que a seguir o paciente apresentou novo colapso circulatorio, sendo novamente recuperado, finalmente a terceira parada cardiaca foi irreversivel e constatou-se o obito intra-operatorio
