Parotid gland tumours are the main tumours of the salivary glands, and more than 80% are benign. The adenoid cystic carcinoma is characterized by its unpredictable behavior and propensity to spread along nerves. Only a limited number of articles have reported cytopathology studies of cystic salivary gland lesions [1518].The largest study to date from Johns Hopkins reviewed 145 FNA cases of cystic major salivary gland lesions in which the majority (84.8%) of patients had follow-up data available [].In this series most (79.3%) cases were non-neoplastic, Overall 5-year survival is 35%, and 10-year survival is approximately 20%.
