Abstract
Lesions of the small airway are observed in a wide variety of pulmonary conditions, most of which are due to infection, tobacco and connective tissue diseases. They are sometimes isolated or, more often, associated with involvement of other pulmonary structures such as the bronchi, the lung parenchyma and the pleura. The pathological spectrum of the bronchiolar response to injury is relatively limited. Thus, the same lesion is observed in various clinical settings. There is no correlation between the severity of the small airway involvement seen by the pathologist and the clinical and functional manifestations of bronchiolitis. The causes of bronchiolitis may be classified on a clinical basis, on aetiology or on histological appearance, yet no single classification appears to be suitable. An integrated clinical, radiological, functional and histological approach is needed. As they are seen by the pathologist microscopically, small airway lesions may be subdivided into three categories: (1) simple nonspecific lesions (bronchiolitis - cellular, follicular, granulomatous, obliterative, constrictive) that are never exclusively related to one clinical picture, (2) or displaying a more specific pattern like the respiratory bronchiolitis of the smoker or the histolgical changes of asthma, (3) bronchiolar lesions in conditions described as "interstitial", predominantly centrilobular, involving the small airways and the lung parenchyma, and visible radiologically. After recalling the normal histological appearances of the bronchioles, this review describes the diversity of the histopathological lesions of the small airways.

Abstract
The connective tissue diseases (CTDs) are inflammatory, immune-mediated disorders in which interstitial lung disease (ILD) is common and clinically important. Interstitial lung disease may be the first manifestation of a CTD in a previously healthy patient. CTD-associated ILD frequently presents with the gradual onset of cough and dyspnea, although rarely may present with fulminant respiratory failure. Infection and drug reaction should always be ruled out. A diagnosis of idiopathic ILD should never be made without a careful search for subtle evidence of underlying CTD. Treatment of CTD-ILD typically includes corticosteroids and immunosuppressive agents.

Abstract
Objective: To study the clinical features of interstitial lung disease (ILD) in patients with dermatomyositis and factors related to its development. Methods: Clinical records for patients with dermatomyositis were reviewed retrospectively. Results: Records were analysed for 230 patients (mean follow-up period, 18 months). The prevalence of ILD was 49.6%. The presence of ILD correlated positively with the presence of arthralgia, myoasthenia and cough, but negatively with the presence of Gottron’s papules. Patients with ILD had poorer pulmonary function and more frequent positivity for anti-Jo1 antibodies than those without ILD. Patients with ILD characteristically showed linear, patchy, ground-glass opacities and reticular computed tomography (CT) patterns, usually at the bottom or apex of the lung. Conclusions: Dermatomyositis patients presenting with heliotrope rash, arthralgia, myoasthenia, cough, dysphagia, anti-Jo1 positivity or abnormal lung function were more likely, whereas those presenting with Gottron’s papules were less likely, to develop ILD. Characteristic CT patterns in dermatomyositis patients with ILD were lines, patches, ground-glass opacities and reticulation.

Abstract
Idiopathic pulmonary fibrosis (IPF), the most common fibrotic lung disease, is a chronic disease of unknown etiology with a very high mortality. Personalized medicine focuses on the use of the individual's molecular and 'omic' (i.e., genomic, epigenomic and proteomic) information to direct more efficient and cost-effective strategies for prevention, diagnosis, outcome prediction and treatment of diseases. In this review, we describe the use and promise of applying 'omic' technologies to the familial and sporadic forms of IPF as a means to personalize diagnosis and outcome prediction in IPF. The validation and implementation of such approaches will be crucial to personalize IPF patient care, prioritize lung transplant and stratify patients for drug studies, as well as, in the future, predict response to therapies as they emerge.

Abstract
UNLABELLED A 64-year old woman with a long standing Sjogren's syndrome was undergoing evaluation for renal transplant surgery when two pulmonary opacities were detected on chest CT. Subsequent biopsy revealed extranodal marginal B-cell non-Hodgkin's lymphoma (NHL). An FDG-PET/CT scan was then performed which demonstrated isolated FDG avid pulmonary involvement. After therapy, FDG-PET/CT scans showed good response to treatment with near complete resolution of FDG avidity. This rare case illustrates the rare pulmonary manifestation of extranodal lymphoma in a patient with Sjogren's syndrome and emphasizes the value of FDG PET/CT in the initial staging and evaluation of response to treatment, which has not previously been published. CONFLICT OF INTEREST None declared.

Abstract
Interstitial lung disease (ILD) is commonly encountered in patients with connective tissue diseases (CTD). Besides the lung parenchyma, the airways, pulmonary vasculature and structures of the chest wall may all be involved, depending on the type of CTD. As a result of this so-called multi-compartment involvement, airflow limitation, pulmonary hypertension, vasculitis and extrapulmonary restriction can occur alongside fibro-inflammatory parenchymal abnormalities in CTD. Rheumatoid arthritis (RA), systemic sclerosis (SSc), poly-/dermatomyositis (PM/DM), Sjögren's syndrome (SjS), systemic lupus erythematosus (SLE), and undifferentiated (UCTD) as well as mixed connective tissue disease (MCTD) can all be associated with the development of ILD. Non-specific interstitial pneumonia (NSIP) is the most commonly observed histopathological pattern in CTD-ILD, but other patterns including usual interstitial pneumonia (UIP), organizing pneumonia (OP), diffuse alveolar damage (DAD) and lymphocytic interstitial pneumonia (LIP) may occur. Although the majority of patients with CTD-ILD experience stable or slowly advancing ILD, a small yet significant group exhibits a more severe and progressive course. Randomized placebo-controlled trials evaluating the efficacy of immunomodulatory treatments have been conducted only in SSc-associated ILD. However, clinical experience suggests that a handful of immunosuppressive medications are potentially effective in a sizeable portion of patients with ILD caused by other CTDs. In this manuscript, we review the clinical characteristics and management of the most common CTD-ILDs.

Abstract
OBJECTIVE To investigate the correlation between ultrasound (US) B-lines and high-resolution computed tomography (HRCT) findings in the assessment of pulmonary fibrosis (PF) in patients with connective tissue disorders (CTD). METHODS Thirty-four patients with a diagnosis of CTD were included. Each patient underwent clinical examination, pulmonary function test (PFT), chest HRCT, and lung US by an experienced radiologist or rheumatologist. A second rheumatologist carried out US examinations to assess interobserver agreement. In each patient, US B-line lung assessment including 50 intercostal spaces (IS) was performed. For the anterior and lateral chest, the IS were the second to the fifth along the parasternal, mid-clavicular, anterior axillary, and medial axillary lines (the left fifth IS of the anterior and lateral chest was not performed because of the presence of the heart, which limits lung visualization). For the posterior chest, the IS assessed were the seventh to the eighth along the posterior-axillary and subscapular lines. The second to eighth IS were assessed in the paravertebral line. In each IS, the number of US B-lines under the transducer was recorded, summed, and graded according to the following semiquantitative scoring: grade 0 = normal (< 10 B-lines); grade 1 = mild (11 to 20 B-lines); grade 2 = moderate (21 to 50 B-lines); and grade 3 = marked (> 50 B-lines). RESULTS A total of 1700 IS in 34 patients were assessed. A significant linear correlation was found between the US score and the HRCT score (p < 0.001; correlation coefficient ρ = 0.875). A positive correlation was found between US B-line assessments and values of DLCO (p = 0.014). Both κ values and overall percentages of interobserver agreement showed excellent agreement. CONCLUSION Our study demonstrates that US B-line assessment may be a useful and reliable additional imaging method in the evaluation of PF in patients with CTD.

Abstract
Collagen vascular diseases are a diverse group of immunologically mediated systemic disorders that often lead to thoracic changes. The collagen vascular diseases that most commonly involve the lung are rheumatoid arthritis, progressive systemic sclerosis, systemic lupus erythematosus, polymyositis and dermatomyositis, mixed connective tissue disease, and Sjögren syndrome. Interstitial lung disease and pulmonary arterial hypertension are the main causes of mortality and morbidity among patients with collagen vascular diseases. Given the broad spectrum of possible thoracic manifestations and the varying frequency with which different interstitial lung diseases occur, the interpretation of thoracic images obtained in patients with collagen vascular diseases can be challenging. The task may be more difficult in the presence of treatment-related complications such as drug toxicity and infections, which are common in this group of patients. Although chest radiography is most often used for screening and monitoring of thoracic alterations, high-resolution computed tomography can provide additional information about lung involvement in collagen vascular diseases and may be especially helpful for differentiating specific disease patterns in the lung. General knowledge about the manifestations of thoracic involvement in collagen vascular diseases allows radiologists to provide better guidance for treatment and follow-up of these patients.

Abstract
Articles in the past have described the radiological appearances of different interstitial lung diseases (ILDs) in varying levels of detail. However, these articles have generally been written for radiologists with a background in basic chest computed tomography (CT) interpretation. This article summarizes a basic approach for diagnosing ILDs on high-resolution CT (HRCT) for the nonradiologist clinician and discusses the most common HRCT features of common ILDs.

Abstract
Pulmonary involvement is second in frequency only to esophageal involvement as a visceral complication of systemic sclerosis (SSc) and has surpassed renal involvement as the most common cause of death. Interstitial lung disease and pulmonary vascular disease, particularly pulmonary arterial hypertension, are the most commonly encountered types of lung involvement. Chronic aspiration, airway disease, neuromuscular weakness, extrinsic pulmonary restrictive pathology, pleural effusions, pneumothorax, and lung cancer cause clinically significant disease and occur commonly enough to be routinely considered in the assessment of the SSc patient with respiratory symptoms. Affected patients have a significantly worse prognosis than patients with SSc who are free of pulmonary involvement.

Abstract
This work was intended to evaluate the prevalence of obstructive small-airway disease in patients with rheumatoid arthritis (RA) and its association with clinical characteristics. Pulmonary function testing (PFT) and high-resolution computed tomography (HRCT) were performed on 189 consecutive RA patients. Each case was diagnosed based on abnormal HRCT findings. We defined obstructive dysfunction of small airways as a forced expiratory flow from 25% to 75% of vital capacity (FEF(25-75)) value >1.96 residual standard deviation (RSD) below predicted values. We found 19 patients (10.1%) with an interstitial pneumonia (IP) pattern and 15 (7.9%) with a bronchiolitis pattern; the other 155 (82.0%) had no abnormal HRCT patterns. In patients with neither abnormal pattern, median values of percentage predicted for carbon monoxide diffusing capacity (DL(CO)) and ratio of DL(CO) to alveolar ventilation (DLco/VA) were within the normal range, but median FEF(25-75), forced expiratory flow at 25% of vital capacity (V(25)), and V(25)/height were <70% of predicted values. Forty-seven patients (30.3%) in this group had obstructive small-airway dysfunction. Multivariate logistic regression analysis indicated that this type of abnormality is strongly associated with respiratory symptoms [odds ratio (OR) 5.18; 95% confidence interval (CI) 1.70-15.75; p = 0.012), smoking history (OR 2.78; 95% CI 1.10-6.99; p = 0.03), and disease duration >10 years (OR 2.86; 95% CI 1.27-6.48; p = 0.012). Parenchymal micronodules, bronchial-wall thickening, and bronchial dilatation on HRCT scans were also predictive factors for abnormal FEF(25-75), although these morphological changes were too limited for us to diagnose these patients with the bronchiolitis pattern. Obstructive dysfunction of small airways is apparently common among RA patients, even among those with neither the IP nor the bronchiolitis pattern on HRCT scans. Factors significantly associated with abnormal FEF(25-75) are respiratory symptoms, smoking history, and RA duration.

Abstract
Pulmonary hypertension may primarily affect either the arterial (precapillary) or the venous (postcapillary) pulmonary circulation. Pulmonary arterial hypertension may be idiopathic or arise in association with chronic pulmonary thromboembolism; pulmonary embolism caused by tumor cells, parasitic material, or foreign material; parenchymal lung disease; liver disease; vasculitis; human immunodeficiency virus infection; or a left-to-right cardiac shunt. Its histologic characteristics include vascular changes-medial hypertrophy, intimal cellular proliferation, intraluminal thrombosis, and the development of plexiform lesions-that manifest primarily in the muscular pulmonary arteries. Features of pulmonary arterial hypertension that may be seen at computed tomography (CT) are central pulmonary artery dilatation, abrupt narrowing or tapering of peripheral pulmonary vessels, right ventricular hypertrophy, right ventricular and atrial enlargement, dilated bronchial arteries, and a mosaic pattern of attenuation due to variable lung perfusion. Pulmonary venous hypertension may result from pulmonary veno-occlusive disease, pulmonary venous compression by extrinsic lesions (eg, mediastinal fibrosis), left-sided cardiac disease, or pulmonary vein stenosis. Its histologic hallmarks include venous intimal cellular proliferation, medial hypertrophy, and thickening of the internal elastic lamina; capillary congestion and proliferation; interlobular septal thickening; lymphatic dilatation; and, sometimes, venous infarction and vascular changes characteristic of pulmonary arterial hypertension. CT scans in patients with pulmonary venous hypertension show pulmonary interstitial and alveolar edema with signs of pulmonary arterial hypertension. High-resolution CT with standard axial and angiographic acquisitions is useful for identifying underlying disorders and differentiating among the various causes of secondary pulmonary hypertension.

Abstract
Scleroderma is a multisystem disease characterized by a severe inflammatory process and exuberant fibrosis. Lung involvement is a frequent complication and a leading cause of morbidity and mortality in this syndrome. Two major pulmonary syndromes are associated with scleroderma; a pulmonary vascular disorder evolving over time into relatively isolated pulmonary arterial hypertension (PAH), and interstitial lung disease (ILD). Each syndrome, when present, is a cause of morbidity and significantly reduces survival of scleroderma patients when compared to patients free of lung complication. When pulmonary hypertension and ILD are combined, survival is further reduced. Current therapy appears to have no meaningful effect on either condition and, thus, there is a need for better understanding of underlying pathogenic mechanisms. This review focuses on clinical, diagnostic, and therapeutic features of PAH and ILD as well as other frequent but less debilitating lung complications of scleroderma.

Abstract
Interstitial lung disease (ILD) is a common manifestation of systemic sclerosis (SSc) mainly encountered in patients with diffuse disease. Unlike idiopathic interstitial pneumonias (IIP), SSc associated ILD corresponds to non-specific interstitial pneumonia (NSIP) in most cases, whereas usual interstitial pneumonia (UIP) is encountered less frequently. This explains the better prognosis of SSc associated ILD compared to IIP. However, severe restrictive lung disease represents one of the two main causes of disease-related death in SSc patients. The treatment of SSc associated ILD is not very well established. Anti-fibrosing treatments have failed to demonstrate any benefit and cyclophosphamide, which has been used in the treatment of this condition for about 15 years, has recently been evaluated in two prospective randomised studies which showed a significant but modest effect on respiratory function. Since none of the patients included in retrospective or prospective studies were selected on the basis of progression of ILD, and since only a minority of SSc patients develop severe ILD, further studies should focus on the subgroup of SSc patients with worsening ILD. A subgroup of patients with rapidly progressive ILD might benefit from pulsed intravenous cyclophosphamide combined with prednisone 15 mg daily but this remains to be confirmed.

Abstract
Interstitial lung disease (ILD) is a common manifestation of systemic sclerosis (SSc) and mainly encountered in patients with diffuse disease and/or anti-topoisomerase 1 antibodies. ILD develops in up to 75% of patients with SSc overall. However, SSc-ILD evolves to end-stage respiratory insufficiency in only a few patients. Initial pulmonary function tests (PFT) with measurement of carbon monoxide diffusing capacity, together with high-resolution computed tomography, allows for early diagnosis of SSc-ILD, before the occurrence of dyspnea. Unlike idiopathic ILD, SSc-ILD corresponds to non-specific interstitial pneumonia in most cases, whereas usual interstitial pneumonia is less frequently encountered. Therefore, the prognosis of SSc-ILD is better than that for idiopathic ILD. Nevertheless, ILD represents one of the two main causes of death in SSc patients. To detect SSc-ILD early, PFT must be repeated regularly, every 6 months to 1 year, depending on disease worsening. Conversely, broncho-alveolar lavage is not needed to evaluate disease activity in SSc-ILD but may be of help in diagnosing opportunistic infection. The treatment of SSc-ILD is not well established. Cyclophosphamide, which has been used for 20 years, has recently been evaluated in two prospective randomized studies that failed to demonstrate a major benefit for lung function. Open studies reported mycophenolate mofetil, azathioprine and rituximab as alternatives to cyclophosphamide. On failure of immunosuppressive agent treatment, lung transplantation can be proposed in the absence of other major organ involvement or severe gastro-esophageal reflux.

Abstract
The presence of pulmonary vasculitis can be suggested by a clinical presentation that includes diffuse pulmonary hemorrhage, acute glomerulonephritis, chronic refractory sinusitis or rhinorrhea, imaging findings of nodules or cavities, mononeuritis multiplex, multisystemic disease, and palpable purpura. Serologic tests, including the use of cytoplasmic antineutrophil cytoplasmic antibody (ANCA) and perinuclear ANCA, are performed for the differential diagnosis of the diseases. A positive cytoplasmic ANCA test result is specific enough to make a diagnosis of ANCA-associated granulomatous vasculitis if the clinical features are typical. Perinuclear ANCA positivity raises the possibility of Churg-Strauss syndrome or microscopic polyangiitis. Imaging findings of pulmonary vasculitis are diverse and often poorly specific. The use of a pattern-based approach to the imaging findings may help narrow the differential diagnosis of various pulmonary vasculitides. Integration of clinical, laboratory, and imaging findings is mandatory for making a reasonably specific diagnosis.

Abstract
Collagen vascular disease is one of the most common causes of chronic infiltrative lung disease. Patterns of lung injury from collagen vascular disease include nonspecific interstitial pneumonia (NSIP), usual interstitial pneumonia, organizing pneumonia, bronchiectasis, obliterative bronchiolitis, and pulmonary arterial hypertension. The prevalence of each entity varies according to the specific disease entity. NSIP and pulmonary hypertension are common in scleroderma, whereas usual interstitial pneumonia, bronchiectasis, and obliterative bronchiolitis are commonly found in rheumatoid arthritis. In systemic lupus erythematosus, pleural effusions and pulmonary hemorrhage are the salient features. In polymyositis, a combination of organizing pneumonia and NSIP is characteristic. Sjögren syndrome is characterized by bronchiectasis and lymphoid interstitial pneumonia, often associated with thin-walled cysts. Ankylosing spondylitis is associated with upper lobe fibrosis, and may be complicated by mycetoma.

Abstract
Pleuropulmonary manifestations of systemic lupus erythematosus (SLE) have been reported to be of variable prevalence, depending on the diagnostic methods used. The objective of this study was to determine the anatomopathological prevalence and the nature of lung involvement associated with SLE and to define if there were differences in the grade and type of pulmonary involvement in patients who had died at different time periods, before or after 1996. Complete autopsy studies of 90 patients with SLE diagnosis carried out between 1958 and 2006 and their clinical records were studied. All patients fulfilled the American College of Rheumathology (ACR) diagnostic criteria for SLE. Two groups of patients were analyzed: patients who had died before 1996 and those deceased in 1996–2006. Some pleuropulmonary involvement was detected in 97.8% of the autopsies. The most frequent findings were pleuritis (77.8%), bacterial infections (57.8%), primary and secondary alveolar haemorrhages (25.6%), followed by distal airway alterations (21.1%), opportunistic infections (14.4%) and pulmonary thromboembolism (7.8%), both acute and chronic. No cases of acute or chronic lupus pneumonitis were found. Opportunistic lung infections were invasive aspergillosis, disseminated strongyloidiasis, mucormicosis and Pneumocystis carinii. Only three of 23 patients with alveolar haemorrhage showed capillaritis. The four patients with primary pulmonary hypertension (PHT) had plexiform lesions. Deceased patients’ age at death (46.09 ± 11.01 vs 30.3 ± 11.5 years, P < 0.0001) as well as survival time from diagnosis date (11.8 ± 11.2 vs 4.4 ± 4.9 years, P < 0.0001) in the second time period evaluated were significantly higher. However, there were no statistically significant differences in the prevalence of any of the pulmonary manifestations. Sepsis was considered the major cause of death without significant differences in both groups. Our results show that pulmonary manifestations directly caused by systemic lupus erythematosus are very uncommon and that their prevalence has not changed in the past 10 years. Pulmonary infection is still the most frequent affection, and it is an important cause of death in patients with lupus.

Abstract
Nonspecific interstitial pneumonia (NSIP) has variable clinical, pathologic, and radiologic manifestations. Cellular and fibrotic NSIP are the two main histologic subtypes and differ from one another in the degree of inflammation and fibrosis. It is important to differentiate NSIP from other diffuse lung diseases, especially usual interstitial pneumonia and hypersensitivity pneumonitis, owing to differences in prognosis and treatment. At high-resolution computed tomography, the most common findings suggestive of NSIP are lower lobe peripherally predominant ground-glass opacity with reticular abnormality, traction bronchiectasis, and lower lobe volume loss. Nodules, cysts, and areas of low attenuation are uncommon and should point one toward other diagnoses. Because many cases of NSIP are associated with collagen vascular diseases, it is important to look for associated findings that may suggest an underlying collagen vascular disease. Given the difficulty clinicians, pathologists, and radiologists experience in making the diagnosis of NSIP, a group approach in which these specialists work together to reach a consensus diagnosis has the highest likelihood of achieving the correct diagnosis.

Abstract
INTRODUCTION Previous studies of interstitial lung disease (ILD) suggest that prognosis and therapeutic response are influenced by the presence of underlying collagen vascular disease (CVD). Yet, what proportion of patients presenting with ILD have CVD is largely unknown. We sought to determine the frequency of a new CVD diagnosis in an ILD referral population. MATERIALS/PATIENTS AND METHODS We retrospectively studied 114 consecutive patients evaluated at the Johns Hopkins Interstitial Lung Disease Clinic for the development of CVD. RESULTS In this retrospective cohort, nearly one-third of the 114 patients with confirmed ILD satisfied published criteria for a CVD diagnosis. Seventeen (15%) patients were diagnosed with a new CVD as a direct consequence of their ILD evaluation. Patients with new CVD diagnosis were younger than those without new CVD diagnosis: 51.4years (95% CI 45-58years) and 60years (95% CI 57-63), respectively (p=0.01). Moreover, an ANA>or=1:640 (p=0.03) and elevated levels of creatine phosphokinase (CPK) or aldolase (p<0.001) were associated with a new CVD diagnosis. CONCLUSIONS Unrecognized collagen vascular disease may be more common than previously appreciated among patients referred with ILD. High titer ANA and an elevated CPK or aldolase are associated with a CVD diagnosis in this referral population.

Abstract
OBJECTIVE The purpose of this study was to analyze the CT findings of interstitial lung diseases that are associated with collagen vascular disease (CVD), with particular attention to nonspecific interstitial pneumonia (NSIP), and to examine whether it is possible to predict the clinical diagnosis of CVDs based on the CT findings alone. METHODS CT scans of 49 patients with NSIP associated with CVD (15 males, 34 females; mean age, 55+/-10 years; age range, 25-76 years) were included in this retrospective study. All patients underwent a surgical biopsy. The clinical diagnosis comprised rheumatoid arthritis (RA) (n=15), systemic sclerosis (SSc) (n=8), polymyositis and dermatomyositis (PM/DM) (n=18), Sjögren's syndrome (SjS) (n=4), and mixed connective tissue disease (MCTD) (n=4). Each CT was reviewed by two independent observers who made a clinical diagnosis based on the CT findings alone. RESULTS The observers made a correct diagnosis for 22 (45%) of the 49 patients. A correct diagnosis was made for: RA in 7 (47%) of 15 patients; SSc in 3 (38%) of 8 patients; PM/DM in 11 (61%) of 18 patients; SjS in 1 (25%) of 4 patients. None of the 4 MCTD cases was diagnosed. CONCLUSION It is difficult to make a correct clinical diagnosis of the various types of CVDs based solely on CT findings. However, it is probable to make a reasonably accurate clinical diagnosis in cases that show the typical CT findings, especially for PM/DM patients.

Abstract
CT is a useful tool for identification of small airways diseases, and it can be used to classify these entities into inflammatory and constrictive bronchiolitis. Inflammatory forms of bronchiolitis include cellular bronchiolitis (usually caused by infection or aspiration), respiratory bronchiolitis, panbronchiolitis, and follicular bronchiolitis. Constrictive bronchiolitis may be caused by previous infection, toxic inhalation, collagen vascular disease, or transplantation. CT also helps categorize chronic obstructive pulmonary disease into emphysema predominant and airway predominant forms.

Abstract
Ectopic or tertiary lymphoid tissues develop at sites of inflammation or infection in peripheral, non-lymphoid organs. These tissues are architecturally similar to conventional secondary lymphoid organs, with separated B and T cell areas, specialized populations of dendritic cells, well-differentiated stromal cells and high endothelial venules. Ectopic lymphoid tissues are often associated with the local pathology that results from chronic infection or chronic inflammation. However, there are also examples in which ectopic lymphoid tissues appear to contribute to local protective immune responses. Here we review how ectopic lymphoid structures develop and function in the context of local immunity and pathology.

Abstract
INTRODUCTION Interstitial lung diseases (ILD) in systemic sclerosis (SSc) are mainly encountered in patients with diffuse disease although they may occur less frequently in patients with limited cutaneous disease. BACKGROUND In SSc early detection of ILD should be achieved by high resolution computed tomography and pulmonary function tests, including measurement of DLCO. In total up to 75% of patients with SSc develop ILD but it is progressive in only a minority of patients. Unlike idiopathic ILD, SSc associated ILD corresponds to non-specific interstitial pneumonia rather than usual interstitial pneumonia in the majority of cases. This explains the better prognosis of SSc associated ILD compared with idiopathic ILD. Nevertheless ILD represents one of the two main causes of death in SSc. VIEWPOINT The treatment of SSc associated ILD is not well established. Anti-fibrosing treatments have failed to demonstrate benefit and cyclophosphamide, which has been used for about 15 years in the treatment of this condition, has recently been evaluated in two prospective randomised studies which showed a significant but modest effect on respiratory function. CONCLUSION A subgroup of patients with rapidly progressive ILD might benefit from pulsed intravenous cyclophosphamide combined with prednisone 15 mg daily, but this remains to be confirmed.

Abstract
PURPOSE In patients with connective tissue diseases (CTD), the early detection and evaluation of the severity of the pulmonary involvement is mandatory. High-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) are considered to be valuable noninvasive diagnostic modalities. Radiopharmaceuticals have also been used for this purpose. Our aim was the evaluation of technetium-labeled human polyclonal immunoglobulin G (HIG) lung scintigraphy in the early detection and assessment of the severity of the pulmonary involvement in CTD patients. METHODS Fifty-two nonsmoking CTD patients were studied by PFTs, HRCT, and HIG. According to PFTs, patients were divided in group A (impaired PFTs-abnormal pulmonary function) and group B (normal pulmonary function). Semiquantitative analysis was done on HIG and HRCT and corresponding scores were obtained. RESULTS Significant difference was found between HIG scores in the two groups (0.6 +/- 0.07 vs 0.51 +/- 0.08, P < 0.001). There was a statistically significant negative correlation between HIG scores and PFTs results and a positive correlation between HIG and HRCT scores. HIG demonstrated similar clinical performance to HRCT. At the best cut-off levels of their score (0.56 and 7, respectively), HIG had a superior sensitivity (77.5 vs 57.5%) with lower specificity (75 vs 91.7%). The combination of the two methods increased the sensitivity of abnormal findings at the expense of specificity. CONCLUSIONS HIG scintigraphy can be used in the early detection and evaluation of the severity of the pulmonary involvement in CTD, whereas, when used in combination with HRCT, the detection of affected patients can be further improved.

Abstract
The aim of the study was to evaluate morphologic alterations of microvessels quantitatively and objectively in patients with various connective tissue diseases (CTD) by means of histomorphometry. Standardized histomorphometrical examination of dermal microvessels was performed by means of interactive semi-automated image analysis in specimens obtained by the technique of capillaroscopically guided nailfold biopsy in 31 patients with various CTD and 8 controls without CTD. Histomorphometry revealed a significant enlargement, an increased dysmorphia and a diminished number of microvessels as well as an increased papillary area in CTD-patients compared to controls. The most severe alterations of microvessels were seen in scleroderma and MCTD, whereas in SLE the morphometrically observed changes were less impressive. By means of histomorphometry morphological changes of the microvasculature can be analyzed quantitatively and objectively. Since differences regarding nature and extent of the microvascular injury between particular conditions can be disclosed by the technique, this approach may be a useful tool to identify distinct patterns of microangiopathy in the various types of CTD.

Abstract
The American Thoracic Society-European Respiratory Society classification of idiopathic interstitial pneumonias (IIPs), published in 2002, defines the morphologic patterns on which clinical-radiologic-pathologic diagnosis of IIPs is based. IIPs include seven entities: idiopathic pulmonary fibrosis, which is characterized by the morphologic pattern of usual interstitial pneumonia (UIP); nonspecific interstitial pneumonia (NSIP); cryptogenic organizing pneumonia (COP); respiratory bronchiolitis-associated interstitial lung disease (RB-ILD); desquamative interstitial pneumonia (DIP); lymphoid interstitial pneumonia (LIP); and acute interstitial pneumonia (AIP). The characteristic computed tomographic findings in UIP are predominantly basal and peripheral reticular opacities with honeycombing and traction bronchiectasis. In NSIP, basal ground-glass opacities tend to predominate over reticular opacities, with traction bronchiectasis only in advanced disease. COP is characterized by patchy peripheral or peribronchovascular consolidation. RB-ILD and DIP are smoking-related diseases characterized by centrilobular nodules and ground-glass opacities. LIP is characterized by ground-glass opacities, often in combination with cystic lesions. AIP manifests as diffuse lung consolidation with ground-glass opacities, which usually progress to fibrosis in patients who survive the acute phase of the disease. Correct diagnosis of IIPs can be achieved only by means of interdisciplinary consensus and stringent correlation of clinical, imaging, and pathologic findings. (c) RSNA, 2007.

Abstract
BACKGROUND Acute exacerbation (AE) in idiopathic pulmonary fibrosis (IPF) is increasingly recognized as a relatively common and highly morbid clinical event. However, clinical data on AE in non-IPF interstitial pneumonia are sparse. This study was performed to find the frequency, clinical features, and outcome of AE in non-IPF interstitial pneumonia. METHODS Retrospective analysis of 10 patients who satisfied the modified Akira criteria for AE during follow-up of 74 patients with surgical lung biopsy-confirmed idiopathic nonspecific interstitial pneumonia (I-NSIP) and 93 patients with biopsy-confirmed interstitial pneumonia associated with collagen vascular disease (CVD-IP). RESULTS AE occurred in six patients with I-NSIP (1-year frequency, 4.2%) and in four patients with CVD-IP (rheumatoid arthritis [RA], n = 3; scleroderma, n = 1), with 1-year frequency of 3.3%. Median age was 58 years (range, 47 to 75); six patients were female. AE occurred in two patients immediately after surgical biopsy. Median duration of acute symptom before hospital admission was 10 days (range, 1 to 30). Median ratio of Pao(2) to the fraction of inspired oxygen (Fio(2)) was 172 (range, 107 to 273), and Pao(2)/Fio(2) ratio was < 200 in six patients. Surgical lung biopsy performed at the time of AE in two patients revealed diffuse alveolar damage superimposed on nonspecific interstitial pneumonia pattern. Four patients with I-NSIP survived to discharge and were followed up for 24 months (range, 6 to 121). CONCLUSION AE occurred in the patients with I-NSIP with apparently better prognosis. In patients with CVD-IP, AE occurred mostly with RA-usual interstitial pneumonia in our small series with poor outcome.

Abstract
Microscopic polyangiitis (MPA) may present with a syndrome that resembles idiopathic pulmonary fibrosis (IPF). We describe an MPA patient with the clinical presentation of a "pulmonary-muscle" syndrome in which interstitial lung disease antedated the onset of myopathy. Identification of vasculitis on muscle biopsy was instrumental in recognizing clinical, radiographic, and histopathologic features that were more characteristic of MPA than of IPF. Institution of glucocorticoid and cyclophosphamide therapy led to the induction of a complete remission. The histologic findings in this case implicate subclinical episodes of alveolar hemorrhage as the mechanism of interstitial lung disease in MPA.

Abstract
We report the autopsy findings of a 40- year- old woman with lung complications of rheumatoid arthritis. She has been suffering from rheumatoid arthritis and interstitial pneumonia without satisfactory therapies because of her poor compliance. At autopsy, diffuse pleural adhesions and many protruding cysts were observed. The cut surfaces had rich fibrous changes and honey-comb like appearances dominantly in the left lower lobe. Microscopically, remarkable fibrous changes were observed with destruction of the alveolar structure. These fibroses were temporally homogeneous and lacked prominent fibroblastic foci. The histological pattern was consistent with fibrous non- specific interstitial pneumonia. In peripheral pulmonary arterioles, some thrombi were detected with much recanalization. Systemic amyloidosis was observed in the submandibular gland, thyroid, heart, and arterioles of the lung, kidney, and digestive tract. In the left pulmonary artery, a large embolus was detected. This embolism was the direct cause of death. Her pulmonary findings, except for the embolism, were considered sober states of lung complications of rheumatoid arthritis without the influence of therapy.

Abstract
Sjogren's Syndrome (SS) is a systemic autoimmune disease characterized by dry eyes (keratoconjunctivis sicca) and dry mouth (xerostomia). To fulfill diagnostic criteria, patients must have objective signs of dryness on examination and laboratory confirmation of an autoimmune process as evidenced by a positive autoantibody to SS-A antigen or a characteristic lip biopsy. SS may exist as a primary condition or in association with other systemic autoimmune disorders (termed secondary SS) such as rheumatoid arthritis, systemic lupus erythematous (SLE), progressive systemic sclerosis (scleroderma), or dermatomyositis. Exclusions to the diagnosis include pre-existing lymphoma, hepatitis C or HIV infection. Pathogenesis involves both genetic (especially HLA-DR) and environmental factors. Both T-cells and B-cells are involved in the generation of cytokines and chemokines within the glands. The epithelial cells of the glands also play a role in pathogenesis. The dermatologic manifestations range from drynessness (sicca) and its complications to vasculitis. There is a significant overlap in the clinical manifestations, as well as treatment, of SS and SLE. However, SS patients require special attention to the complications of ocular dryness (keratocojunctivitis sicca and blepharitis) and oral dryness (rapid tooth loss and oral candidiasis) SS patients have a markedly increased risk of lymphoma and enlarged lymph nodes or persistently enlarged parotid/submandibular glands that require further evaluation.

Abstract
Diffuse parenchymal lung diseases are a group of disorders that involve the space between the epithelial and endothelial basement membranes and are generally segregated into four major categories. These include the idiopathic interstitial pneumonias, which are further categorized into seven clinical/radiologic/pathologic subsets. These disorders generally share a common pattern of physiologic abnormality characterized by a restrictive ventilatory defect and reduced diffusing capacity (DLCO). Pulmonary function testing is often used and recommended in their assessment and management. The potential clinical application of physiologic testing includes to aid in diagnosis, although its value in differential diagnosis is limited. Pulmonary function testing also aids in establishing disease severity and in defining prognosis. In nonspecific interstitial pneumonia and idiopathic pulmonary fibrosis, severely decreased DLCO has proven valuable in this regard. Similarly, exertional desaturation to less than 88% at baseline testing and a decrease in FVC (greater than 10%) over the course of short-term follow-up identify patients at particular risk of mortality. Finally, physiologic testing, especially spirometry and DLCO, have demonstrated value in monitoring response to therapy and identifying disease progression.

Abstract
OBJECTIVE Many chronic diseases exhibit characteristic pulmonary distribution patterns, but the underlying biologic explanations remain elusive. On the basis of emerging evidence from systems biology, we propose that gradients of T helper immune function exist as an epiphenomenon of the hypoxic pulmonary vasoconstriction response. Regional variation of immune function may contribute to preferential distribution patterning of lung diseases. CONCLUSION The lungs represent but one example in which the distribution of immune function throughout the body may explain disease location. This hypothetic framework can apply to diseases outside the realm of pulmonary biology and illustrates the potential benefit of integrating advances in systems biology and medical imaging.

Abstract
Interstitial lung disease is a serious complication of polymyositis/dermatomyositis and leads to death from chronic respiratory insufficiency in 30 to 66% of cases. It is a criterion of poor prognosis in these disorders. Its onset occurs at variable points in the course of polymyositis/dermatomyositis, and precedes them in half of all cases. Presentation may also vary: acute (25%), insidious (60%), or infraclinical, discovered fortuitously (15%). The examinations of choice for early screening are high-resolution computed tomography (CT) and pulmonary function tests, which should be performed during the initial work-up and during ongoing surveillance. Moreover, high-resolution CT also makes it possible to determine the type of histologic lesions in the interstitial lung disease. Today, diagnosis of this disease does not generally require histological confirmation; nonspecific interstitial lung disease seems to be the most common histologic form of lung damage in polymyositis/dermatomyositis (40 to 80%). Anti-Jo1 antibodies are a sensitive marker of interstitial lung disease during polymyositis/dermatomyositis, and close surveillance of lung function is recommended in patients with these autoantibodies. Systematic testing for them is also justified in patients with apparently idiopathic interstitial lung disease, to rule out underlying polymyositis/dermatomyositis. No clear treatment protocols have been established for interstitial lung disease during polymyositis/dermatomyositis. Corticosteroid treatment is the first choice. Its combination with cyclophosphamide may be most effective in corticosteroid-resistant forms of polymyositis/dermatomyositis, especially when begun early; it may also be appropriate to begin corticosteroids as soon as factors predicting poor prognosis are detected.
