title: Unusual mass in the parapharyngeal space: a Warthin's tumour.
abstract: Parapharyngeal space (PPS) tumours are uncommon and can be a diagnostic challenge as the presenting symptoms are often vague and non-specific. Most of the PPS tumours are salivary tumours (pleomorphic adenoma being the most frequent diagnosis), and are thought to originate from minor salivary glands or the deep lobe of the parotid gland. Warthin's tumour, another benign salivary tumour involving the PPS has been rarely reported. A case of bilateral, metachronous Warthin's tumour involving the PPS is reported here. PPS Warthin's tumour is a very rare condition that if undiagnosed may result in considerable morbidity.
