Simultaneous nasopharyngeal and parotid gland Warthin's tumour: a case report. [Un caso raro di tumore di Warthin sincrono della ghiandola parotide e del rinofaringe]

Herein, a rare case of synchronous cystoadenolymphoma (Warthin’s tumour) of the right parotid gland and the nasopharyngeal space is described. Although Warthin’s tumour (WT) of the parotid gland is a common benign pathology, the occurrence of extra-parotid cystoadenolymphoma is rare. Extra-parotid WT have been mainly localised in the submandibular gland, periparotid region and occasionally in other sites, such as the oral cavity, hard palate and nasopharynx. The simultaneous occurrence of an intra-parotid and extra-parotid WT localisation, as in the case presented, is extremely uncommon.
