[Rare tumors of the gallbladder and bile ducts. A case review]. / Vzácné tumory zlucníku a zlucových cest. Kazuistika.

The authors deal with the problem of benigh tumours of the bile duct which might occur as a very suprising intraoperative finding instead of preoperatively diagnosed "gallstones". This situation can happen because of possible mistakes that might accompany today's modern practical investigative techniques. The presented report is an example of the pre-operatirely assumed choledocholithiasis which was not confirmed during the operation. Instead a rare bile duct tumour was found.
