Synchronous gastric and colonic MALT-lymphoma in coeliac disease: a long-term follow-up on gluten-free diet.

We describe the first case of synchronous gastric and colonic mucosa-associated lymphoid tissue lymphoma in coeliac disease. After refusing any other treatment, the patient started a gluten-free diet but a re-evaluation 3 years later failed to demonstrate improvement of the gastric neoplasia on a gluten-free diet, whilst the colonic mucosa-associated lymphoid tissue lymphoma behaviour was unknown (the patient refused a new colonoscopic evaluation).
