Coeliac disease and small bowel carcinoma.

Small bowel carcinoma can occur in association with villous atrophy in the jejunum. In most reported cases there is doubt as to which of these represents the primary lesion. These cases are reviewed here. A further case is reported in which a carcinoma developed in a patient known to be suffering from coeliac disease for some years, although he was not on a gluten-free diet for the time preceding the diagnosis of carcinoma. On dietary restriction he remains well at 2-year follow-up. Possible aetiological factors are discussed.
