Repeated negative biopsies in isolated high-grade cystic duct dysplasia with progression to adenocarcinoma.

Cystic and bile duct dysplasia is a rare histological finding, especially when found in the absence of an underlying malignancy. We report a patient who presented with jaundice and weight loss. Clinical and cytological evidence suggested a diagnosis of cholangiocarcinoma and the patient underwent a pancreatico-duodenectomy.
