[Multifocal presentation of cystadenolymphoma (Warthin tumor) in the parotid gland and larynx].

Warthin's tumour of the larynx is an unusual finding. In present literature only four cases have been described. A fifth case of a 77-year-old woman suffering from Warthin's tumour of the left parotid gland and the left false cord is presented. Moreover, this patient had an inner and outer laryngocele. This combination of Warthin's tumour of the larynx with a laryngocele has not been described before in literature. The theories about the development of Warthin's tumours are discussed, in particular their relationship to the development of the branchial cleft apparatus.
