title: Villous adenomas of the duodenum.
abstract: A patient with multiple villous adenomas of the duodenum is described. Endoscopy plays an essential role in the management of these neoplasms. If no evidence of invasive malignancy is found on multiple endoscopic biopsies, wide local excision is the initial procedure of choice. Invasive malignancy found in either the endoscopic biopsy or the surgical specimen is indication for pancreaticoduodenectomy.
