An unexpected find of multifocal extranodal marginal zone lymphoma

In this case report we describe a patient who was diagnosed with extranodal marginal zone lymphoma (EMZL) at two different body sites, namely at the mucosa of the stomach and the lung. Since the patient presented with a main complaint of dyspnoea, this was a rather unexpected medical finding. To our knowledge, this is even the first case of multifocal EMZL in which the coexistent involvement of the stomach and lung is extensively documented. All medical and technical investigations that were performed during diagnosis and staging are described whilst discussing the typical characteristics of these kinds of lymphomas as stated in current guidelines and literature.
