Pleuroparenchymal fibroelastosis (PPFE) is a rare, idiopathic interstitial pneumonia. wherein the first symptom might be dyspnea or a dry cough. The condition can also be manifested with chest pain secondary to pneumothorax. While the definitive diagnosis is based on a histological evaluation (which is not often performed), a computed tomography scan shows findings, such as apical fibrosis and pleural thickening of the apical lobes, which help assess the diagnosis. We describe a case of PPFE diagnosed radiologically in a 69-year-old man. This case highlights that PPFE is a pathology that can go unnoticed for a long time, and patients might neglect the revealing symptoms such as coughing.

Primary pulmonary lymphoma (PCL) is rare and represents only 0.5-1% of the malignant lung tumour. Pulmonary MALT lymphoma is the most common histological aspect. The pathophysiological mechanism remains poorly known, unlike other locations of MALT lymphoma, no pathogen has so far been associated with the lung localization of the disease. It is characterized by slow evolution and atypical clinical presentation which delays diagnosis. The form «pneumonic» on the imaging allows to evoke the diagnosis while the confirmation is based on the immunohistochemical study which detects the presence of positive CD20 cell. Therapeutic options include surveillance of indolent types of LPP, surgery in localized tumors, chemotherapy in diffuse forms. We report two observations of diagnosed pulmonary MALT lymphoma on a scanno-guided bronchial and pulmonary biopsy.
