The disease concept of idiopathic BOOP has emerged from a study of many open lung biopsy cases of diffuse infiltrative lung disease. The histopathologic features of idiopathic BOOP have several components: bronchiolitis obliterans, organizing pneumonia, accumulation of foamy cells in the peripheral air spaces, and interstitial infiltration of mononuclear cells. These pathologic findings are non...

Among the idiopathic interstitial pneumonias, the two entities— idiopathic pulmonary fibrosis (IPF) characterised by the presence of the usual interstitial pneumonia pattern of histopathology (IPF/UIP) and non-specific interstitial pneumonia (NSIP; same nomenclature for the histopathological pattern and idiopathic disease)—have provoked considerable debate. IPF/ UIP and NSIP closely mimic each ...

Amyopathic dermatomyositis (ADM) is a clinical subtype of dermatomyositis, characterized by the absence of motor weakness and the presence of normal muscle enzyme levels. ADM is sometimes accompanied by interstitial pneumonia that shows a rapid progressive course associated with a poor prognosis. We describe a 70-year-old man who presented rapidly progressive interstitial pneumonia associated w...

We report a case of serious complications following computed tomography (CT)-guided radiofrequency ablation (RFA) performed for the treatment of lung cancer with interstitial pneumonia. The patient developed delayed-onset pyopneumothorax, which required 6 months of antibiotic treatment, drainage, and video-assisted thoracoscopic debridement. Although CT-guided RFA is a promising, effective proc...

I n recent years, there have been important advances in the understanding of diffuse parenchymal lung diseases, especially in relation to the idiopathic interstitial pneumonias, including idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia. Among other diffuse parenchymal lung diseases, the topics of particular interest centred on hypersensitivity pneumonia, parenchymal disease...

Idiopathic pleuroparenchymal fibroelastosis is a rare idiopathic interstitial pneumonia. It was first described in 2004 and subsequently included in the ATS/ERS classification of idiopathic interstitial pneumonia in 2013. There have been few cases reported so far. The diagnostic criteria is still emerging and its etiology is being questioned. We report a case of pleuroparenchymal fibroelastosis...

1. The administration of alcohol produces no evident histological changes in the lungs of mice. 2. Following inhalations of pneumococci the organisms are not visible histologically in the lungs of mice either in the bronchi or alveoli. 3. In partially immunized mice which have been exposed to a pneumococcus spray while alcoholized, true lobar pneumonia not infrequently develops. 4. The primary ...

Results Most of the patients came from rural area (60%). 55% of them were female and 45% were male. We had 3 groups of acute pneumonia: lobar pneumonia (39%), interstitial pneumonia (47%) and bronchopneumonia (14%). More than half of the patients had bacterial pneumonia (70%). From these, 68% had unknown etiology. The most affected ranges were the age group 51-55 and 61-65. Most cases of acute ...
