Warthin's tumour (papillary cystadenoma lymphomatosum) of the parotid gland is characteristically:
- A Malignant with a high recurrence rate
- B Exclusively unilateral, arising from the deep lobe
- C Bilateral and multifocal in up to 10% of cases, associated with smoking ✓
- D Avid on PET-CT due to high glucose metabolism
Correct answer: C. Bilateral and multifocal in up to 10% of cases, associated with smoking
Explanation
Warthin's tumour (adenolymphoma) is a benign parotid neoplasm that is bilateral and multifocal in ~10% of cases; it has a well-established association with cigarette smoking. It arises virtually exclusively in the parotid (superficial lobe/tail region) and is avid on Tc-99m pertechnetate scan but not particularly on FDG-PET. It is benign with very low recurrence after excision.
