Mucosa-associated lymphoid tissue lymphoma simulating Crohn’s disease: A case report

Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma and Crohn‘s disease require different treatments, but both diseases can cause similar gastrointestinal symptoms and have no definitive diagnostic tests. The goal of this case report is to promote the more attentive attitude of gastroenterologists to the rare cases of lymphomas. In the presented case of a 52-year-old patient with a previous diagnosis of the small intestine Crohn's disease and good response to the corresponding treatment, the MALT lymphoma had a rare presentation form–an ulcer, while most MALT lymphomas appear as a mass. This circumstance has made it very difficult to make a correct diagnosis.
