Abstract:
Celiac disease (CD) is an autoimmune disease triggered by gluten in the diet. The association between CD and increased risk of neoplasia is described mainly in patients diagnosed with CD and aged over 40 years or during the first years after CD diagnosis. Patients who remain symptomatic after 12 months of gluten-free diet should be screened to exclude neoplasms, especially lymphoma and gastrointestinal neoplasms. We report a case of small bowel adenocarcinoma (SBA) in a patient diagnosed with CD one year earlier.
