We report on the unusual course of disease in three patients with gastrointestinal MALT lymphoma. Special features are the primary lymphoma manifestation, the high-grade transformation during the follow up, the long-time interval between initially curative intended therapy and relapse and the occurrence of another neoplasia in one case. This demonstrates that despite their good prognosis in general, follow-up investigations of gastrointestinal MALT lymphoma are reasonable.
