Two sisters with coeliac disease and jejunal cancer: just a coincidence?

ABSTRACT

Two sisters with asymptomatic coeliac disease are described; they both developed a primary jejunal cancer at the same age. While screening the family, a third sister was found to have coeliac disease, but without detectable cancer in the small intestine or stomach. These findings suggest an increased susceptibility in this family for carcinoma developing secondary to asymptomatic coeliac disease. We conclude that the finding in a patient of the combination of coeliac disease and malignancy in the digestive tract is sufficient reason to investigate the first-degree relatives with regard to the presence of coeliac disease and a secondary carcinoma.
