Plasmacytoma of the ileum complicating Crohn's disease: report of a case and review of the literature.

Portions of the gastrointestinal tract involved with Crohn's disease are at increased risk of undergoing neoplastic change. Most of these neoplasms are adenocarcinomas. We recently encountered the first reported patient with a solitary plasmacytoma of the ileum arising in an area of preexisting active Crohn's disease. This case is presented along with a review of the literature dealing with lymphoproliferative disorders in bowel affected with Crohn's disease.
