Sample itemA 40-year-old woman has a painless, slowly growing mobile mass in the parotid for years. What is the most likely tumour?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Pleomorphic adenoma
Pleomorphic adenoma is the commonest salivary tumour, usually in the parotid, with epithelial and myxochondroid components. Enucleation risks recurrence, so superficial parotidectomy is preferred.

Correct. This is the commonest salivary neoplasm.
C. Warthin tumour
Warthin tumour occurs in older male smokers and is often bilateral.
