Malignant tumours of the small bowel are uncommon in clinical practice. Adenocarcinoma is the most common of these tumours, accounting for approximately 35-45% of all tumours. It may occur sporadically, in association with familial adenomatous polyposis coli or Peutz-Jeghers syndrome or hereditary non-polyposis colorectal cancer, or in association with chronic inflammatory bowel changes (such as Crohn's disease or celiac disease).
