As Kelsey and Brown2 have remarked, there is unusual difficulty in summarizing the literature of this subject. Tumors are not always classified alike by surgeons and pathologists, and carcinoma of this region has at times probably been confounded with sarcoma and endothelioma. Many carcinomas reported as having their origin elsewhere may have been primary in the nasopharynx. From all available reports, these authors estimate the relative frequency of tumors of the nasopharynx as: carcinoma, 30 per cent.; sarcoma, 60, and endothelioma, 10 per cent. Some are of the opinion that endotheliomas are more frequent.3
