title: Inflammatory Polyp of the Gallbladder Mimicking Early Polypoid Carcinoma.
abstract: We treated a 69-year-old male with a 16-mm polyp of the gallbladder. Enhanced computed tomography demonstrated marked enhancement. With a tentative diagnosis of early polypoid cancer of the gallbladder, open cholecystectomy was performed. Intraoperative ultrasound showed hyperechoic spots on the surface of the polyp with an inner echopenic area. The histological diagnosis was an inflammatory polyp that manifested nonneoplastic, edematous stroma, and infiltration of lymphcytes and plasmacytes.
