Evaluation of fine needle aspiration cytology of salivary glands: an analysis of 141 cases.
141 salivary gland lesions that were subjected to fine needle aspiration (FNA) cytology at the University Hospital, Kuala Lumpur, from January 1993 to October 2000 were reviewed with a view to assess the sensitivity and utility of cytological diagnosis in diseases of salivary glands. The highest number of cases was seen in the sixth decade of life. There was no gender preponderance in salivary gland neoplasms except in Warthin's tumours that occurred predominantly in males. The parotid gland was the most frequent salivary gland needled. Seven cases (5%) presented with bilateral salivary gland enlargement. Cytological study yielded a neoplastic diagnosis in 74.5% cases. Of the neoplastic lesions, 71.4% could be definitely designated as benign and 25.7% as clearly malignant. Pleomorphic adenoma and acinic cell carcinoma were the most common benign and malignant neoplasms diagnosed respectively. 53 cases had histological correlation; of these, 49 (92.5%) were neoplastic. The overall diagnostic accuracy of FNA cytological diagnosis in salivary gland lesions was found to be 73.6%.
