Lymphoepitheliomas of the larynx (undifferentiated carcinomas of nasopharyngeal type).
Three cases of lymphoepitheliomas of the larynx are reported. This type of carcinoma--which occurs almost exclusively in nasopharynx--is very unfrequent in the larynx (0.2%). In the 3 cases, the tumors arose in a ventricular diverticulum which presented the same lymphoepithelial structure as the tonsils. Under such conditions, these lymphoepitheliomas, which have to be called 'undifferentiated carcinomas of nasopharyngeal type' are believed to develop from the lymphoepithelial tissue of the laryngocele.
