[Simultaneous laryngeal carcinomas: a case report and review of literature].
The high incidence of second primary malignant neoplasms in patients under treatment for head and neck tumors has been well documented in literature. In these cases the second primary reappears still in the upper aero-digestive tract or in distant organs (lung, esophagus, stomach, skin,....). The Authors report a case of a male, 64 year old patient, a moderate drinker and smoker, with two distinct simultaneous laryngeal malignant neoplasms. One tumor, which arose on the laryngeal face of the epiglottis, was a verrucous carcinoma (Ackerman's tumor); the other neoplasm, on the right vocal cord, was a well differentiated squamous cell carcinoma. Microlaryngeal examinations and TC-scans revealed a normal, uninvolved right false vocal cord and the Morgagni's ventricle. After surgical therapy, serial laryngeal samples were removed and underwent immunohistochemical studies. Microscopic examination revealed that the anterior commissure, the pre-epiglottic and paraglottic spaces were intact, furthermore, monoclonal antibody studies proved that the two simultaneous laryngeal cancers were independent. In the discussion the Authors report some clinical considerations, a review of literature concerning multiple simultaneous laryngeal tumours and emphasize the concept of "field cancerization", first described with regard to the oral cavity by Slaughter.
