Although a wide variety of malignant tumors may arise in the nasopharynx, only
squamous cell carcinoma is considered in this discussion because management of
the others varies substantially with histology. Subdivisions of squamous cell carcinoma in
this site include lymphoepithelioma (Schminke tumor); transitional cell tumors,
well to poorly differentiated grade; and keratinizing or nonkeratinizing
variety. The presence of keratin has been associated with reduced local
control and survival.
