This time, we studied clinically 33 cases who were histopathologically diagnosed as having parotid tumors during the 6-year period from 1991 to 1996. Of the 33 cases with parotid tumor, 29 cases (88%) had benign tumor and 4 cases (12%) had malignant tumor. In terms of histological type, 15 cases with pleomorphic adenoma accounted for majority of cases with benigh tumor, and malignant tumors consisted of one case each of adenoid cystic carcinoma, moderately differentiated squamous cell carcinoma, acinic cell carcinoma and malignant lymphoma. We studied clinical symptoms, therapeutic methods and clinical courses in these cases.
