Polymorphic adenoma (PA) is the most common and the Warthin tumour (WT) is the second most common parotid gland tumour. Although these are mostly benign lesions, their biological behaviour differs with PA being relatively aggressive with a malignant tendency and a higher recurrence rate after resection. PA is seen in 30-50 years of age, more commonly in females, and is usually located in the superficial lobe of the parotid gland whereas the WT is usually seen in the middle-aged and elderly men (>50 years of age), associated with smoking and can be bilateral1.
