[Mucosa-associated lymphoid tissue-derived (MALT) lymphoma]. / Lymphome de type Mucosa-Associated Lymphoid Tissue, (MALT) pulmonaire, puis gastrique.

Pulmonary Mucosa-Associated Lymphoid Tissue (MALT)-type lymphoma is the most frequent primary pulmonary lymphoma. We report the case of a patient who presented a pulmonary MALT-type lymphoma treated with chloraminophen, with a recurrence 5 years later characterized with pulmonary lesions associated with a gastric location. This observation underlines some anatomical and clinical aspects of pulmonary MALT-type lymphoma, and leads to discuss the evolution of its physiopathological and therapeutic concepts. In particular, the contributions of positron emission tomography and molecular biology allow the analysis of possible multifocal affections of this disease.
