Fine needle aspiration cytology(FNAC) is widely used in screening of head and neck masses because it has high accuracy and few damage. FNAC were performed on 235 patients with head and neck mass at our institute during 5 years, one hundred eighty eight of 235 patients were proven histologically or clinically. The cytologic findings of 202 aspirates obtained by the fine needle aspiration technique from the head and neck masses were compared with the histology of the permanent section and the results of clinical follow-up. The results obtained were as follow ; 1) FNAC for head and neck masses shows the overall concurrence rate of 78.2% and the overall diagnostic accuracy of 51.5%. 2) FNAC for malignant head and neck masses, malignant lymph nodes, malignant lesions of soft tissue, bone & oral cavity shows concurrence rate of 82.9%, 76.7%, 83.8% and diagnostic accuracy of 61.8%, 75.0%, 75.0%, respectively. 3) FNAC for malignant and benign salivary gland tumors shows concurrence rate of 62.5%, 73.7% and diagnostic accuracy of 50.0%, 57.9%, respectively. 4) FNAC for tuberculosis shows diagnostic accuracy of 45.1%.
