Extraglandular Warthinʹs tumours: clinical evaluation and long-term follow-up

Nine patients with extraglandular cystadenolymphoma (Warthinʹs tumour) were treated between 1965 and 1995 at the Department of Otorhinolaryngology, University of Gottingen. This number corresponds to 2.7% of all Warthinʹs 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 patientsʹ clinical data and documents therapeutic success. Our results show the complete absence of recurrences after surgical excision of extraglandular cystadenolymphomas.
