Enterocolic fistula associated with an intestinal lymphoma.

Abstract

Introduction Enterocolic fistulas are usually caused by inflammatory conditions such as inflammatory bowel disease (eg, Crohn's disease). This abnormal communication can also be caused by prior surgery, foreign bodies, pancreatitis, diverticulitis, and, most ominously, by malignancy. The following case describes an elderly patient with failure to thrive and new-onset diarrhea who underwent colonoscopic examination; findings on colonoscopy revealed a large intestinal lymphoma with an associated enterocolic fistula.
