Case Discussion

The management and follow-up of gallbladder polyps is controversial and practice varies between centers. However, due to the increased risk of malignancy, polyps measuring 10mm or greater should be considered for cholecystectomy 1.

This patient underwent cholecystectomy and a gallbladder adenoma with low-grade dysplasia was confirmed by histopathology.
