The histopathology of the small bowel, mesenteric nodes and peritoneal deposit all contains adenocarcinoma of the jejunum.

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 tumor 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.
