Abstract:
Mucosa-associated lymphoid tissue (MALT) lymphoma is a form of low-grade malignant B-cell extranodal non-Hodgkin's lymphoma. It is classified as marginal-zone lymphoma and represents less than 1% of all lung cancer. We describe a case of MALT lymphoma limited exclusively to the lung that came to our attention with infective pleural effusion and concomitant lung consolidation of the left lower lobe. Our case demonstrates that MALT can begin with an acute clinical presentation. The clinical scenario, with fever, parietal chest pain, and leukocytosis, suggested an infective process. Radiological and sonographic examinations and the endoscopic aspect during medical thoracoscopy (MT) were typical of an infective etiology. The histological outcome of non-specific inflammatory pleuritis confirmed our suppositions. However, the missing resolution of lung consolidation after several weeks led us to an alternative diagnosis. Parenchymal biopsies obtained by bronchoscopy allowed us to reach the correct diagnosis: MALT lymphoma limited to the lung.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
