Irregular narrowing and dilation of the biliary duct system produces the characteristic beaded pattern seen on cholangiogram. Malignant degeneration resulting in cholangiocarcinoma is a well\u2010recognized sequela of PSC. Bile duct brushing cytology is the primary screening technique for cholangiocarcinoma. It is associated with a relatively low sensitivity but high specificity. Few false positive bile duct brushings have been reported in the literature, with the majority of these having occurred in a background of PSC. We report two patients with PSC in whom bile duct brush cytologies were falsely positive for carcinoma. Diagn.
