title: Concurrent diagnosis of Crohn's disease and colorectal carcinoma in a young man with abdominal pain.
abstract: The lead time between diagnosis of Crohn's disease and presentation with a Crohn's related malignancy is generally twenty years from diagnosis. This case outlines that of a young man who presented to the emergency department with abdominal pain and was subsequently discovered to have a malignant stricture complicating underlying Crohn's disease that was previously quiescent and undiagnosed. It demonstrates that a new diagnosis of Crohn's disease does not rule out previously quiescent underlying disease and therefore risk of colrectal carcinoma.
