Small Intestinal Adenocarcinoma in a Patient With Celiac Disease.

ABSTRACT

Celiac disease (CD) is a systemic immune-mediated disorder against gluten, leading to an autoantibody response causing damage to the small intestinal mucosa. CD has been associated with gastrointestinal malignancies, most commonly gastrointestinal lymphoma. Rare malignancies have also been reported, such as small intestinal adenocarcinoma. In this report, we present a case of a 91-year-old male with a history of CD, noncompliant with a gluten-free diet, who presented with weight loss, abdominal pain, and gastrointestinal bleeding secondary to a newly discovered adenocarcinoma of the jejunum.
