ABSTRACT
Endobronchial metastasis secondary to follicular thyroid carcinoma is extremely rare. Here, we report a case of follicular thyroid cancer in 58-year-old male who presented with hemoptysis. Computed tomography of the chest revealed multiple lung metastases. Flexible fiberoptic bronchoscopy revealed a fragile polypoid mass 5 cm distal to the vocal cords; biopsy taken from this mass revealed follicular thyroid carcinoma.

From December 2004 until November 2005, 15 cases of endobronchial cancer presenting with 22 episodes of mechanical obstruction of the airway, difficulty in breathing, hemoptysis, severe coughing, obstructive pneumonia and identified recurrent atelectasis of the lungs. The cancer was removed rapidly, effectively and without complication by a technique of fiberoptic bronchoscopic electrocautery.

Se presenta el caso de un paciente de 66 años de edad con antecedente de tabaquismo moderado en su juventud y padecimiento de un mes de evolución, caracterizado por disfagia al inicio a sólidos y después de 20 días a líquidos. Tenía síndrome de derrame pleural izquierdo de 100 por ciento. Se manejo mediante toracocentesis y pleurodesis química por recidiva del derrame, el cual persistió en 30 por ciento. El reporte histopatológico fue de adenocarcinoma bronquial primario

O autor tece consideraçöes gerais sobre as lesöes precursoras do carcinoma epidermoide do epitélio bronquial. Rever a estrutura básica da mucosa bronquial e estuda a formaçäo da metaplasia escamosa a partir de células basais e de células epiteliais mucosas. Descreve os diversos graus de atipias celulares (leve, moderada e avançada) bem como o carcinoma in situ. A citomorfologia das lesöes epiteliais precursoras é descrita tanto no esputo como em espécimens de escovado brônquico
