Malignant fistula of the small bowel to the colon is rare and is most often due to adenocarcinoma. Small bowel lymphoma is unusual, representing less than 1 percent of all gastrointestinal malignancies. We report a case of intestinal lymphoma presenting with diarrhea and abdominal pain. A jejunocolic fistula was discovered during colonoscopy. Celiotomy revealed a large, ulcerated fistula tract between the jejunum and distal transverse colon, and pathology was consistent with peripheral T-cell lymphoma. This is a rare entity in a nonimmunocompromised individual and has not been previously described in Korea.
