Malignant lymphoma in ulcerative colitis. Report of a case.

The authors present the case of a 40-year-old woman with primary malignant lymphoma complicating chronic ulcerative colitis. Twenty-one cases reported in the literature are reviewed and the various available data analyzed. Variations in the distribution of lymphoma in both the normal and colitic bowel supports a relationship between both conditions. Any lymphocytic infiltrate seen in biopsies obtained from ulcerative colitis should be assessed to exclude associated lymphoma. The prognosis is poor.
