The pathologies included 173 cases(91.5%)of squamous cell carcinoma, 4 of malignant lymphoma, 4 of lymphoepithelial carcinoma, 3 of carcinoma in situ, 2 of spindle cell carcinoma, 2 of basaloid squamous cell carcinoma, and 1 of carcinoma ex pleomorphic adenoma. Squamous cell carcinoma including its variants accounted for 180 cases(95.2%). There were 185 cases(97.9%)of epithelial tumors, on the other hand, only 4 cases(2.1%)of non-epithelial tumors involved malignant lymphoma.
