Synchronous extra-parotid Warthin's tumour

Warthin's tumour (also known as adenolymphoma or papillary cystadenoma lymphomatosum) is benign and accounts for 12 per cent of all neoplasms of the parotid gland. A case of extra-parotid Warthin's tumour occurring synchronously in a peri-parotid lymph node is described. This is not a metastatic phenomenon and occurs as a result of salivary gland inclusions of local lymph nodes during the embryological development of the parotid. Extra-parotid Warthin's tumour should be regarded as a benign incidental finding and the prognosis is excellent.
