Extraglandular Warthin's tumours: clinical evaluation and long-term follow-up

Nine patients with extraglandular cystadenolymphoma (Warthin's tumour) were treated between 1965 and 1995 at the Department of Otorhinolaryngology, University of Göttingen. This number corresponds to 2.7% of all Warthin's tumours treated at our clinic so far. Although this rare tumour is well documented by case reports, a controlled follow-up study has not yet been published to the best of our knowledge. The retrospective investigation presented here gives the patients' clinical data and documents therapeutic success. Our results show the complete absence of recurrences after surgical excision of extraglandular cystadenolymphomas.
