Clinical observations in 123 cases of salivary gland tumors (carcinoma: 11, pleomorphic adenoma: 81, warthin's tumor: 31) between 1991 and 2000 are reported and the cytodiagnosis of fine needle aspirated cytological materials from 114 cases (carcinoma: 10, pleomorphic adenoma: 78, warthin's tumor: 30) are discussed.<br>Results and conculusions were as follows:<br>1. In warthin's tumor, possible cytological classification diagnosis of benign tumor (class II) was made in 90% (27 cases), histological type suspicious diagnosis of warthin's tumor in 90% (27 cases) and 3 cases yielded unsatisfactory materials.<br>2. In pleomorphic adenoma, we were possible classification diagnosis of benign tumor (class IIIa-II) was made in 91.9% (68 cases), histological diagnosis of pleomorphic adenoma in 90.5% (67 cases) and 6 cases yielded unsatisfactory material.<br>3. In carcinoma cases, possible cytological classification diagnosis (class V-IIIb) of malignannt tumor was made in 50% (5 cases), histological type diagnosis of carcinoma in only 30% (adeno carcinoma: 2 cases, sucamous cell ca: l case) and 2 cases yielded unsatisfactory materials.<br>4. Overall cytological results showed a sensitivity of 62.5%, specifity of 100%, false negative findings in 37.5%, false positive findings in 0% and unsatisfactory materials in 9.6%.<br>5. When reexamination of malignant 10 cases was attemped postoperatively, it confirmed correct cytological diagnosis in 2 cases of adenoidcystic ca and a case of mucoepidermoid ca. Thus the cytological sesitivity rate rose from 62.5% to 75.0%.<br>6. FNAC (Fine Needle Aspiration Cytology) for salivary gland tumor is a useful diagnostic method, becase the differential diagnosis of benign or malignant tumor and suspicious diagnosis of histologic type are possible.
