Multiple synchronous carcinoma of the aero-digestive tract

Multiple carcinoma of the upper aerodigestive tract is an increasingly recognized problem, and a concept of 'field cancerization' has been proposed to explain this phenomena. The initial assessment of a patient with an isolated aerodigestive carcinoma must be extensive so as not to miss any synchronous lesions, and may include radiography and endoscopy. Treatment cannot be standardised but must be tailored to suit individual problems and because of the high incidence of metachronous tumours, follow-up must be both thorough and 'lifelong'. A case of three primary synchronous squamous carcinomas of the upper aerodigestive tract is presented. The relevant literature is reviewed.
