[Duodenal villous adenoma: a case report]

Small bowel tumours are rare neoplasms representing just 1% of all the gastrointestal tract lesions. Adenomas are the benign forms which, developing in the duodenum, tend to localize in periampullary region, with high incidence of malignant degeneration. The authors report a case of a fifty-five-years old woman with a periampullary villous adenoma.
