Idiopathic LIP is a lymphocytic infiltration of the alveolar interstitium and airspaces with no known cause 1; Classified as a rare interstitial pneumonia 2; Patients with LIP rarely experience progression of the disease to pulmonary fibrosis 3 LIP, lymphoid interstitial pneumonia. Acute interstitial pneumonia is an extremely severe idiopathic acute interstitial disease, characterized by a histopathological pattern of diffuse alveolar damage, the exudative phase of which is defined by interstitial and intra-alveolar edema, formation of hyaline membranes, and diffuse alveolar infiltration of inflammatory cells. Radiology. Phase 1 (derivation group) identified smoking-related features in patients with a history of smoking (n=41). Sumikawa H, Johkoh T, Ichikado K, et al. 2006;241:258–66. Idiopathic pleuroparenchymal fibroelastosis C- Unclassifiable idiopathic interstitial pneumonias 5. Non-specific interstitial pneumonia (NSIP) is an interstitial lung disease that may be idiopathic or secondary to connective tissue disease, toxins or numerous other causes. Idiopathic nonspecific interstitial pneumonia: prognostic significance of cellular and fibrosing patterns—survival comparison with usual interstitial pneumonia and desquamative interstitial pneumonia. Potential causes (see table Causes of Interstitial Lung Disease) are assessed systematically. A bacteria called Mycoplasma pneumoniae is the most common cause. 7) Idiopathic lymphoid interstitial pneumonia (LIP) 8) Idiopathic pleuroparenchymal fibroelastosis (PPFE) Unclassifiable idiopathic interstitial pneumonias. Idiopathic pulmonary fibrosis. Non-specific Interstitial Pneumonia 6. Pneumonias are often thought of as infections, but these diseases do not appear to result from infection. IDIOPATHIC INTERSTITIAL PNEUMONIA— PART 2: SPECIFIC DISEASE ENTITIES SERIES EDITORS: TAMERA J CORTE, ATHOL U WELLS AND HAROLD R COLLARD Acute and subacute idiopathic interstitial pneumonias HIROYUKI TANIGUCHI AND YASUHIRO KONDOH Department of Respiratory Medicine and Allergy, Tosei General Hospital, Seto, Aichi, Japan ABSTRACT Idiopathic NSIP is a rare diagnosis and requires exclusion of these other possible causes. Idiopathic pulmonary fibrosis is the clinical term for usual interstitial pneumonia. with suspected idiopathic interstitial pneumonia were referred to the study center by participants in the University of Michigan Fibrotic Lung Disease Network (see acknowledgment). Idiopathic Lymphoid Interstitial Pneumonia – Insights in ILD. Idiopathic NSIP is a rare diagnosis and requires exclusion of these other possible causes. Nonspecific interstitial pneumonia (NSIP) is a rare disorder that affects the tissue that surrounds and separates the tiny air sacs of the lungs. Chronic Fibrosing Idiopathic Interstitial Pneumonias Marie-Christine Aubry, M.D. Three clinicians, two radiologists, and two pathologists reviewed 58 consecutive cases of suspected idiopathic interstitial pneumonia. 10,47,48 NSIP accounts for 14% to 35% of biopsies performed for chronic interstitial pneumonia. Seth Kligerman, M.D. 1. Because most cases of lymphoid interstitial pneumonia are associated with other conditions, true idiopathic lymphoid interstitial pneumonia is rare . Allen P. Burke, M.D. The word idiopathic means of unknown cause, so when the cause of interstitial lung disease is not identified, idiopathic interstitial pneumonia is diagnosed. Am J Surg Pathol 2000; 24:19. Some of the known common causes include toxins, environmental factors, chronic diseases, cancer, and infections.Depending on the cause, interstitial lung disease can resolve or may lead to irreversible scarring and damage to the lungs. Idiopathic interstitial pneumonia should be suspected in any patient with unexplained interstitial lung disease. Idiopathic interstitial pneumonias (IIPs) are histopathologically classified into several types, including usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP) and cryptogenic organising pneumonia (COP). Am J Surg Pathol 2000; 24: 19–33. The idiopathic interstitial pneumonias (IIPs) are diffuse interstitial lung diseases of unknown cause. NSIP is a chronic interstitial lung disease characterized by relatively homogeneous expansion of the alveolar walls by inflammation and/or fibrosis. Martinez: Idiopathic Interstitial Pneumonias 83 Figure 3. They are characterized by cellular infiltration of the interstitial compartment of the lung with varying degrees of inflammation and fibrosis. Daniil ZD, Gilchrist FC, Nicholson AG, et al. Through the course of evaluation all patients underwent a history, physical examination, complete pulmonary function testing, HRCT, and surgical lung biopsy. Idiopathic pulmonary fibrosis (IPF) Connective tissue disease-associated ILD (CTD-ILD) Rare idiopathic interstitial pneumonias. The exact cause of interstitial lung disease is not always known (idiopathic). It can be distinguished clinically from other types of interstitial pneumonia by the rapid onset of respiratory failure in a patient without preexisting lung … Tissue Disease-associated Interstitial Lung Disease” proposed classification criteria for a new research category defined as “Interstitial Pneumonia with Autoimmune Features” (IPAF). Bacteria, viruses, or fungi can infect the interstitium. idiopathic pulmonary fibrosis (IPF) and nonspecific interstitial pneumonia (NSIP), respiratory bronchiolitis–interstitial lung disease (RB-ILD) and desquamative interstitial pneumonia (DIP), and cryptogenic organizing pneumonia (COP) and acute interstitial pneumonia (AIP) were entered into the … Cigarette smoking is a key factor in the development of numerous pulmonary diseases. A structured, clinicopathological approach to the diagnosis of idiopathic interstitial pneumonia, with particular attention to the identification of idiopathic pulmonary fibrosis, ensures proper therapy, enhances prognosis, and allows for further investigation of … We investigated whether periostin, a matrix protein, could be used as a biomarker to assess histopathological types of IIPs. Idiopathic interstitial pneumonias (IIPs) are diffuse interstitial lung diseases of unknown cause. This page includes the following topics and synonyms: Idiopathic Interstitial Pneumonia, Idiopathic Pulmonary Fibrosis, Usual Interstitial Pneumonia, Desquamative Interstitial Pneumonia, Respiratory Bronchiolitis, RB-ILD, Acute Interstitial Pneumonia, Hamman-Rich Disease, Nonspecific Interstitial Pneumonia. [1, 2] AIP is histologically characterized by diffuse alveolar damage with subsequent fibrosis. All Idiopathic Chronic Lung Disease aRe Nonspecifically Patterned; The mnemonic reflects the frustration of trying to differentiate them on plain film.
