Video: Histopathological approach to patterns of interstitial

The histological pattern of usual interstitial pneumonia, the most frequently seen pattern in biopsies from patients with idiopathic pulmonary fibrosis/cryptogenic fibrosing alveolitis, appears to be comparatively rare. Furthermore, any biopsy showing a combination of histological patterns, a pattern of non-specific interstitial pneumonia or a pattern of lymphoid interstitial pneumonia/follicular bronchiolitis should be thoroughly investigated for a background connective tissue disorder, if. Nonspecific interstitial pneumonia. This histopathology pattern was described by Katzenstein and Fiorelli in 1994 20 in a series including 64 patients. The authors introduced the concept of temporally and spatially homogeneous interstitial fibrosis in direct contrast to the temporal and spatial heterogeneity expected in UIP. For the diagnosis, findings typical of other IIPs had to be absent. Design: - Patients with idiopathic interstitial pneumonia at the University of Chicago who underwent surgical lung biopsy or lung transplantation were assessed for IPAF histopathologic features, using the initial pathology interpretation in the electronic records. A focused rereview of available slides by a pulmonary pathologist was then performed for patients who failed to meet IPAF criteria on initial pathology assessment Fibroblastic focus (FF) is the typical histopathological feature of idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP). A study was undertaken to analyse FF at diagnosis, to analyse the histopathological findings at necropsy, and to examine their association with the course of the disease

Usual interstitial pneumonia (UIP) is the prototypic chronic interstitial pneumonia with temporally heterogeneous interstitial fibrosis and honeycombing (both microscopic and macroscopic), originally described by Liebow and Carrington.16 Patients with cryptogenic fibrosing alveolitis have UIP on surgical lung biopsy.17 UIP is characterised by zones of normal lung tissue adjacent to zones of advanced architectural remodelling .18 The latter is recognised by confluent and dense scarring. Results: The histopathologic patterns were diverse: 10 patients with the UIP pattern, 6 patients with the NSIP pattern, and 2 patients with inflammatory airway disease with the organizing pneumonia pattern. RA preceded ILD in the majority of patients (n = 12). In three patients, ILD preceded RA; in three patients, both conditions were diagnosed simultaneously. The majority (n = 13) of patients had a restrictive defect with or without low diffusion capacity of the lung for carbon monoxide (D. CFA can be subdivided into prognostically significant histopathologic patterns, including nonspecific interstitial pneumonia (NSIP). We reviewed 78 patients with a clinicopathologic diagnosis of CFA, biopsied between 1978 and 1989, to evaluate the prevalence and prognostic significance of these histopathologic patterns, in particular NSIP. Biopsy appearances were reclassified by two pulmonary histopathologists as usual interstitial pneumonia (UIP) (47%), NSIP (36%), or desquamative. Differentiating among the various interstitial lung diseases (ILDs) involves a summation of clinical, physiologic, radiologic, and, when available, histopathologic information ().Although studies have demonstrated that subclinical stages of ILD (termed interstitial lung abnormalities [ILAs]) can be detected by chest computed tomography (CT) in research participants with no diagnosis of ILD (2.

Interstitial Pneumonia With Autoimmune Features: Value of

  1. Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. The scarring (fibrosis) involves the supporting framework (interstitium) of the lung. UIP is thus classified as a form of interstitial lung disease
  2. A case of giant cell interstitial pneumonia (GIF) that occurred in association with exposure to nitrofurantoin is presented. While the diagnosis of GIP is confirmed by histopathology, this diagnosis can be supported by the findings of bizarre multinucleated giant cells (MGC), elevated T lymphocytes, and a low
  3. Because the nonspecific interstitial pneumoniapattern (NSIP), a newly defined subgroup of idiopathic interstitial pneumonias (IIP) has better prognosis than the usual interstitial pneumonia pattern (UIP), we postulated that NSIP may occur more frequently than UIP in patients with scleroderma who develop fibrosis. Method: We reviewed the pathologic, radiologic and clinical outcomes in 19 patients with PF-SSc. Two pulmonary pathologists reclassified the histopathology of surgical lung biopsies.
  4. The histopathologic features of an idiopathic, non-specific interstitial pneumonia (NSIP) pattern observed on surgical lung biopsy (SLB) have also been thought to be the pulmonary manifestation of this process. 1,2 Demonstration of an NSIP pattern or a usual interstitial pneumonia (UIP) pattern has been shown to be of prognostic value in patients with idiopathic interstitial pneumonias (IIPs). 3 In addition to these diverse histologic patterns, the association of IIP with the.
  5. The non-specific interstitial pneumonia (NSIP) pattern at HRCT and/or histopathology (41 and 25%, respectively) was the most frequent finding in several series (10, 14-17). However, Oldham et al. found a higher prevalence of the UIP pattern (55% at HRCT; 74% on surgical lung biopsy), an observation that was due to the patient recruitment profile of these centers ( 12 )

  4. Familial interstitial pneumonia. Although there is no consensus definition, in the research setting FIP is usually defined as a case of ILD in which the patient also has a family history of two or more relatives with ILD [8, 9].Early studies suggested that familial forms of the disease accounted for 2-4% of IPF [10, 11], although later evidence suggests that this percentage may be higher [12.

Lymphoid interstitial pneumonia (LIP) is regarded as both a disease and a nonneoplastic, inflammatory pulmonary reaction to various external stimuli or systemic diseases. It is an uncommon condition with incidence and prevalence rates that are largely unknown.

Desquamative interstitial pneumonia, abbreviated DIP, is a diffuse lung disease that is strongly associated with smoking.. The term desquamative interstitial pneumonia is a misnomer.The airspace cells that characterize the condition were once thought to represent desquamated epithelial cells, but they are now know to represent macrophages After exclusions, diagnostic histopathology and RNA sequence data from 90 patients were used to train a machine learning algorithm (Envisia Genomic Classifier, Veracyte, San Francisco, CA, USA) to identify a usual interstitial pneumonia pattern. The primary study endpoint was validation of the classifier in 49 patients by comparison with diagnostic histopathology. To assess clinical utility. new term, interstitial pneumonia with autoimmune features (IPAF), to describe individuals with both ILD and combinations of other clinical, serologic, and/or pulmonary morphologic features which putatively stem from an underlying systemic autoimmune condition, but do not meet current rheumatologic criteria for a characterised CTD; and 2) a description of the proposed classification. It has become obvious that several interstitial lung diseases, and even viral lung infections, can progress rapidly, and exhibit similar features in their lung morphology. The final histopathological feature, common in these lung disorders, is diffuse alveolar damage (DAD). The histopathology of DAD is considered to represent end stage phenomenon in acutely behaving interstitial pneumonias.

Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause, primarily occurring in older adults, limited to the lungs, and associated with the histopathologic and/or radiologic pattern of usual interstitial pneumonia (UIP). [] It causes lung scarring, which, over time, results in reduced oxygen intake To evaluate computed tomography (CT) findings of nonspecific interstitial pneumonia (NSIP) based on the current classification of idiopathic interstitial pneumonias (IIPs) and elucidate a characteristic of previously diagnosed NSIP excluded from the current classification. The study included 74 patients with biopsy-proven NSIP (idiopathic NSIP [I-NSIP], 39 patients; NSIP associated with. Introduction. Interstitial pneumonia is a well-recognized manifestation of polymyositis (PM) and dermatomyositis (DM) found in 5-46% of patients [ 1].Interstitial pneumonia is frequently associated with increased mortality and morbidity, and is listed in some studies as the most common cause of death [ 2, 3].The reported mortality of PM/DM with interstitial pneumonia is as high as 50% at 5.

Desquamative interstitial pneumonia (DIP) is one of the rarest of the idiopathic interstitial pneumonias. It is characterized by the accumulation of macrophages in large numbers in the alveolar spaces associated with interstitial inflammation and/or fibrosis. The macrophages frequently contain light brown pigment, and because of their association with smoking have been called 'smoker's. Lymphocytic interstitial pneumonia (LIP) is also a benign lymphoproliferative lung disease characterized by severe lymphocytic infiltration of the alveolar septae . Patients with LIP are also often associated with collagen vascular diseases, immunological diseases, immunodeficiency diseases, lung infections, and drug induced diseases. When FB and LIP are pathologically diagnosed, exclusion of. Interstitial lung disease is a common manifestation of rheumatoid arthritis; however, little is known about factors that influence its prognosis.

Desquamative interstitial pneumonia (DIP) is an uncommon disease characterized by interstitial inflammation and a striking accumulation of macrophages in the alveoli. It is important to recognize that desquamative interstitial pneumonia has distinctive clinical features, prognosis, and response to treatment. The patients are younger than those. The histopathology of the now 'major' and 'rare' IIP is presented here with exposition of the newly included entity of a distinctive upper lobe fibrotic lung disease referred to as idiopathic pleuroparenchymal fibroelastosis. The 'rare histological patterns' of acute fibrinous and organizing pneumonia and bronchiolocentric patterns of interstitial pneumonia are illustrated and discussed The preferred term at present is idiopathic interstitial pneumonia, age is not a reliable predictor of histopathology. Symptoms are identical for all subgroups, with the typical patient reporting progressive dyspnea for months to years and a chronic, nonproductive cough. Physical examination will often reveal digital clubbing and the presence of bibasilar fine inspiratory crackles (Velcro. correlations between the histopathology and clinical characteristics were analysed. The quality of chronic inflammatory and fibrotic changes was expressed according to the 2002 ATS/ERS consensus classification of IIPs. Results: Two patients were diagnosed as having bronchiolitis obliterans organising pneumonia (BOOP)-like lesions, five as having cellular non-specific interstitial pneumonia.
