Case Discussion
Primary adenocarcinoma of the small bowel is about 50 times less common than colonic carcinoma.
One of the more common methods of presentation is with a intusseception, the tumour acting as a lead-point. A chief differential in an adult is small bowel lymphoma.
The commonest site for a small bowel adenocarcinoma is the dudoneum, followed by jejunum as in this case.
