Abstract
Biliary stenosis can present a diagnostic and therapeutic challenge, leading to delays in diagnosis and treatment when distinguishing between benign and malignant stenosis.

We present the case of a 78-year-old man with suspicion of perihilar cholangiocarcinoma based on imaging examinations, who was indicated for curative surgical treatment. Perioperatively, a surprising operative finding of numerous intrahepatic calculi was observed. Definitive cytological examination ruled out cholangiocarcinoma. This case report, along with the ongoing highly reported false positivity of histological findings in surgical specimens, highlights the need to improve the specificity of preoperative evaluations of biliary stenosis (Fig. 9, Ref. 15).
