[Urogenital expression of a tumor of the terminal ileum].

Malignant tumors of the small bowel are usually associated with digestive and general symptoms. We report the case of a 26-year-old patient who presented with right lumbar pain and right testicular pain. Final diagnosis was lymphoma of the terminal ileum involving the right pelvic ureter and the right vas deferens. We discuss frequency and mechanisms of this very unusual extension of malignant small bowel tumors.
