[Carcinoma in Zenker's diverticulum (author's transl)].

Carcinoma arising in Zenker's diverticulum have to be thought of, if it has been present for long time, if there is blood mixed the food regurgitated, and if there are irregularities of the wall of the diverticulum to be detected radiologically. In most cases resection is the method of choice. A case of a 70 year old patient is reported, who harbored a microcarcinoma in the mucosa of a resected Zenker's diverticulum. Surgery was done 10 years ago and no recurrence or mestastases have been observed since.
