In primary sclerosing cholangitis, gallbladder polyps are frequently malignant

Abstract

In conclusion, gallbladder neoplasms in PSC patients are malignant in approximately 40-60% of the cases. The presence of gallbladder epithelial cell dysplasia suggests a dysplasia-carcinoma sequence in PSC similar to that observed in ulcerative colitis. Consideration should be given to performing a cholecystectomy in PSC patients with gallbladder polyps. If a cholecystectomy is not performed, careful interval follow-up is warranted.
