title: Lymphoma creating colojejunal fistula: report of a case and review of the literature.
abstract: Malignant fistula of the colon to the small bowel is rare and is most often due to adenocarcinoma. Colonic lymphoma is unusual, representing only 0.5 percent of all colonic malignancies. We report a case of intestinal lymphoma presenting with diarrhea and malnutrition. A colojejunal fistula was discovered during colonoscopy by biopsy of small bowel through a fistula in the sigmoid colon. Celiotomy revealed a 12 cm mass in the sigmoid colon with a fistula to the jejunum. Pathology was consistent with T-cell lymphoma. This is a rare entity in a nonimmunocompromised host and has not been described in the English literature.
