Abstract
Little is known about the light phenotype of SARS-CoV-2 pneumonia, which behaves in an unusual way, unlike other known respiratory diseases. We believe that the histopathological features of early COVID-19 could be considered the pathophysiological hallmark of this disease. Lung cryobiopsies show almost pristine alveoli, enlarged/hyperplasic alveolar capillaries along with dilatation of the post capillary pulmonary venules. Hypoxemia could therefore be explained by a reduction of the normal V/Q ratio, due to blood overflow around well ventilated alveoli. This could clarify typical manifestations of type L COVID-19, such as happy hypoxemia, response to awake prone positioning, response to PEEP/CPAP and platypnea orthodeoxia.

Abstract
BACKGROUND The pathogenetic steps leading to Covid-19 interstitial pneumonia remain to be clarified. Most postmortem studies to date reveal diffuse alveolar damage as the most relevant histologic pattern. Antemortem lung biopsy may however provide more precise data regarding the earlier stages of the disease, providing a basis for novel treatment approaches. OBJECTIVES To ascertain the morphological and immunohistochemical features of lung samples obtained in patients with moderate Covid-19 pneumonia. METHODS Transbronchial lung cryobiopsy was carried out in 12 Covid-19 patients within 20 days of symptom onset. RESULTS Histopathologic changes included spots of patchy acute lung injury with alveolar type II cell hyperplasia, with no evidence of hyaline membranes. Strong nuclear expression of phosphorylated STAT3 was observed in >50% of AECII. Interalveolar capillaries showed enlarged lumen and were in part arranged in superposed rows. Pulmonary venules were characterized by luminal enlargement, thickened walls, and perivascular CD4+ T-cell infiltration. A strong nuclear expression of phosphorylated STAT3, associated with PD-L1 and IDO expression, was observed in endothelial cells of venules and interstitial capillaries. Alveolar spaces macrophages exhibited a peculiar phenotype (CD68, CD11c, CD14, CD205, CD206, CD123/IL3AR, and PD-L1). CONCLUSIONS Morphologically distinct features were identified in early stages of Covid-19 pneumonia, with epithelial and endothelial cell abnormalities different from either classical interstitial lung diseases or diffuse alveolar damage. Alveolar type II cell hyperplasia was a prominent event in the majority of cases. Inflammatory cells expressed peculiar phenotypes. No evidence of hyaline membranes and endothelial changes characterized by IDO expression might in part explain the compliance and the characteristic pulmonary vasoplegia observed in less-advanced Covid-19 pneumonia.

Abstract
INTRODUCTION The accurate diagnosis of individual interstitial lung diseases (ILD) is often challenging, but is a critical determinant of appropriate management. If a diagnosis cannot be made after multidisciplinary team discussion (MDTD), surgical lung biopsy is the current recommended tissue sampling technique according to the most recent guidelines. Transbronchial lung cryobiopsy (TBLC) has been proposed as an alternative to surgical lung biopsy. METHODS This prospective, multicentre, international study analysed the impact of TBLC on the diagnostic assessment of 128 patients with suspected idiopathic interstitial pneumonia by a central MDTD board (two clinicians, two radiologists, two pathologists). The level of confidence for the first-choice diagnoses were evaluated in four steps, as follows: 1) clinicoradiological data alone; 2) addition of bronchoalveolar lavage (BAL) findings; 3) addition of TBLC interpretation; and 4) surgical lung biopsy findings (if available). We evaluated the contribution of TBLC to the formulation of a confident first-choice MDTD diagnosis. RESULTS TBLC led to a significant increase in the percentage of cases with confident diagnoses or provisional diagnoses with high confidence (likelihood ≥70%) from 60.2% to 81.2%. In 32 out of 52 patients nondiagnostic after BAL, TBLC provided a diagnosis with a likelihood ≥70%. The percentage of confident diagnoses (likelihood ≥90%) increased from 22.7% after BAL to 53.9% after TBLC. Pneumothoraces occurred in 16.4% of patients, and moderate or severe bleeding in 15.7% of patients. No deaths were observed within 30 days. INTERPRETATION TBLC increases diagnostic confidence in the majority of ILD patients with an uncertain noninvasive diagnosis, with manageable side-effects. These data support the integration of TBLC into the diagnostic algorithm for ILD.

Abstract
BACKGROUND Transbronchial lung cryobiopsy (TBLC) has been introduced recently in the diagnosis of interstitial lung diseases. We aimed to evaluate the prognostic significance of the distinction between idiopathic pulmonary fibrosis and other interstitial lung diseases with the use of TBLC data in multidisciplinary team (MDT) diagnosis. METHODS In this single-centre, retrospective, investigator-initiated comparative study, we evaluated consecutive patients without a definite usual interstitial pneumonia pattern on high-resolution CT, who presented to the GB Morgagni Hospital (Forlì, Italy), and who underwent TBLC (Jan 1, 2011, to Dec 31, 2014) or surgical lung biopsy (SLB; Jan 1, 2002, to Dec 31, 2016). Three pathologists reviewed the specimens, masked to clinical information. MDT evaluation was done before and after biopsy. The primary endpoint was the prognostic significance of the MDT diagnostic separation between idiopathic pulmonary fibrosis and other interstitial lung diseases in patients undergoing TBLC. Mortality was evaluated by means of Cox regression analysis. FINDINGS We evaluated 500 consecutive cases, 426 of which were included: 266 had TBLC and 160 had SLB. 189 patients had idiopathic pulmonary fibrosis, 143 had other fibrotic interstitial lung diseases, and 94 had non-fibrotic interstitial lung diseases. Patients undergoing TBLC had more comorbidities and better preserved lung function compared with those undergoing SLB; among patients with a final MDT diagnosis of idiopathic pulmonary fibrosis, patients undergoing TBLC were older, had more comorbidities, and had a different post-biopsy treatment profile than those who received SLB. The distinction between idiopathic pulmonary fibrosis and other interstitial lung diseases made by MDT diagnosis on the basis of TBLC biopsy had clear prognostic significance, with a 5-year transplant-free survival of 68% (95% CI 57-76) in patients with an MDT idiopathic pulmonary fibrosis diagnosis based on TBLC compared with 93% (87-96) in patients without an idiopathic pulmonary fibrosis diagnosis based on TBLC (hazard ratio 5·28, 95% CI 2·72-10·04; p<0·0001). This distinction remained statistically significant in a multivariate analysis controlling for age, sex, smoking status, comorbidities, pulmonary function, and high-resolution CT patterns (p=0·02). INTERPRETATION TBLC makes an important diagnostic contribution in interstitial lung disease, on the basis of the prognostic distinction between idiopathic pulmonary fibrosis and other interstitial lung diseases when TBLC findings are included in multidisciplinary diagnosis. FUNDING None.

Abstract
Introduction Malignant lymphoproliferative disorders are rarely observed in the lung and, considering their clinical and radiological heterogeneity, diagnosis is often difficult and may require invasive methods. Transbronchial cryobiopsy has been confirmed as a new tool in the diagnosis of interstitial lung diseases, given its fewer risks and costs compared to surgical approach. This study is aimed at assessing the effectiveness of cryobiopsy in the diagnosis of lymphoproliferative disorders. Materials and methods Among 970 consecutive cryobiopsies, performed between January 2011 and June 2018 at Morgagni Hospital of Forlì, Italy, 13 cases of lymphoproliferative disorders were collected. Results In 12 out of 13 cases a precise pathological diagnosis could be reached with the support of immunohistochemistry (IHC) and molecular ancillary studies. In the only case in which cryobiopsy did not lead to a definitive diagnosis, the subsequent surgical biopsy also did not help to clarify the diagnosis. Severe bleeding or pneumothorax did not occur in any case. On average, five biopsies were obtained per case, with a mean total area of 1161 mm2, and only 5 out of 65 specimens were inadequate for diagnosis. Instant freezing did not produce tissue artefacts nor did it affect IHC and molecular tests. In all cases the amount of available tissue was sufficient for all ancillary studies. Conclusions Transbronchial lung cryobiopsy is safe and effective for diagnosis in patients with suspected pulmonary involvement by lymphoproliferative disorders and it should therefore be considered a valid alternative to surgical biopsy in such cases. Cryobiopsy is an effective method in the diagnosis of lymphoproliferative disorders. Transbronchial cryobiopsy allows immunohistochemical and molecular analysis. No severe bleeding or pneumothorax were observed in this study.https://bit.ly/2zdHPTn

Abstract
Bronchiolitis manifests as a variety of histological features that explain the complex clinical profiles and imaging aspects. In the period between January 2011 and June 2015, patients with a cryobiopsy diagnosis of bronchiolitis were retrospectively retrieved from the database of our institution. Clinical profiles, imaging features and histologic diagnoses were analysed to identify the role of cryobiopsy in the diagnostic process. Twenty-three patients with a multidisciplinary diagnosis of small airway disease were retrieved (14 females, 9 males; age range 31-74 years old; mean age 54.2 years old). The final MDT diagnoses were post-infectious bronchiolitis (n = 5), constrictive bronchiolitis (n = 3), DIPNECH (n = 1), idiopathic follicular bronchiolitis (n = 3), Sjogren's disease (n = 1), GLILD (n = 1), smoking-related interstitial lung disease (n = 6), sarcoid with granulomatous bronchiolar disorder (n = 1), and subacute hypersensitivity pneumonitis (n = 2). Complications reported after the cryobiopsy procedure consisted of two cases of pneumothorax soon after the biopsy (8.7%), which were successfully managed with the insertion of a chest tube. Transbronchial cryobiopsy represents a robust and mini-invasive method in the characterization of small airway diseases, allowing a low percentage of complications and good diagnostic confidence.

Abstract
Interstitial lung disease (ILD) in systemic sclerosis (SSc) is a major cause of morbidity and mortality, mostly presenting as non-specific interstitial pneumonia. Little is known about the prevalence of pleuroparenchymal fibroelastosis (PPFE), a specific entity affecting the visceral pleura and subpleural parenchyma. We set out to estimate PPFE prevalence in two large cohorts of SSc patients and to assess its impact on survival and functional decline.A total of 359 SSc patients, derived from two referral centres in two different countries (UK and Italy), were included. The first available high-resolution computed tomography scan was independently evaluated by two radiologists blind to clinical information, to quantify ILD extent, freestanding bronchial abnormalities, and lobar percentage involvement of PPFE on a four-point categorical scale. Discordant scores were adjudicated by a third scorer. PPFE extent was further classified as limited (≤2/18) or extensive (>2/18). Results were evaluated against functional decline and mortality.The overall prevalence of PPFE in the combined SSc population was 18% (11% with extensive PPFE), with no substantial difference between the two cohorts. PPFE was significantly linked to free-standing bronchial abnormalities (61% versus 25% in PPFE versus no PPFE; p<0.0001) and to worse survival, independently of ILD severity or short-term lung function changes (HR 1.89, 95% CI 1.10-3.25; p=0.005).In the current study, we provide an exhaustive description of PPFE prevalence and clinical impact in the largest cohort of SSc subjects published so far. PPFE presence should be carefully considered, due to its significant prognostic implications.

Abstract
Pulmonary vein stenosis (PVS) is a rare condition, often difficult to diagnose and associated with poor prognosis at advanced stages. Lung parenchymal abnormalities are indirect evidence of PVS and can manifest as multifocal opacities, nodular lesions, unilateral effusions, and interstitial septal thickening. These can lead to erroneous diagnoses of airway disease, pneumonia, malignancy or interstitial lung disease. This review summarizes the current literature about the approach, evaluation and management of these patients. Our case report demonstrates that PVS is an under-recognized complication of cardiovascular surgery and should be considered in all patients presenting with respiratory symptoms after a cardiac procedure.

Abstract
OBJECTIVE To evaluate, via a multidisciplinary approach, a distinctive paleopathological condition believed to be fibrous dysplasia, found on a 19th/20th century skeleton from Certosa Monumental Cemetery, Bologna, Italy. MATERIALS A skeletonized cranium and mandible recovered from an ossuary in 2014. METHODS Pathological alterations were analysed by radiological examination, dental macrowear, histopathological and genetic analyses. RESULT The skeleton is believed to be an adult male. Differential diagnoses include Paget's disease, McCune-Albright syndrome, osteochondroma and osteosarcoma. The radiographic findings, along with the solitary nature of the lesions, are strong evidence for the diagnosis of fibrous dysplasia (FD). Genetic analysis further revealed a frequency of ˜1% of mutant alleles with the R201C substitution, one of the post-zygotic activating mutation frequently associated with FD. CONCLUSIONS The multi-analytical method employed suggests a diagnosis of monostotic form of FD. The diagnostic design incorporates multiple lines of evidence, including macroscopic, histopathological, and genetic analyses. SIGNIFICANCE Through the use of a multi-analytic approach, robust diagnoses can be offered. This case serves as one of the oldest examples of FD from an historical context. The genetic mutation detected, associated with FD, has not been previously reported in historical/ancient samples.

Abstract
Background: Prognostic evaluation in idiopathic pulmonary fibrosis (IPF) may be important as it can guide management decisions, but the potential role of honeycomb changes in providing information about outcome and survival of patients with IPF, particularly if diagnosed using cryobiopsy, has not been evaluated. Aim of this study was to determinate whether a relationship exists between honeycombing on cryobiopsy and clinical/radiological picture and outcome in patients with IPF and to assess whether the same pathologic criteria that have been used to define the UIP pattern (usual interstitial pneumonia) for surgical biopsy can also be applied to cryobiopsy. Methods: Sixty-three subjects with a multidisciplinary diagnosis of IPF and a UIP pattern on cryobiopsy were evaluated. Patients were classified into two sub-groups depending on the presence of honeycombing on histology. Results: The presence of honeycombing on cryobiopsy did not identify a specific phenotype of patients as it did not correlate with radiological and clinical picture and it was not associated neither with the risk of death (p = 0. 1192) or with the event-free survival (p = 0.827); a higher number of samples and the presence of pleura on biopsy were instead associated with an increase in the finding of honeycombing. Conclusions: The same pathologic criteria that have been used to define the UIP pattern in surgical biopsies (with honeycombing changes considered as non-mandatory for the definition of the pattern itself) can be applied to cryobiopsy samples, as the presence of these changes do not define different clinical or radiological phenotypes of patients with IPF.

Abstract
BACKGROUND Idiopathic pulmonary fibroelastosis (iPPFE) is a rare lung lesion characterized by pleural and subpleural parenchymal thickening due to accumulation of fibroelastotic tissue. Only recently, a few cases with a peribronchiolar distribution of fibroelastotic tissue have been reported. These lesions are more prominent in the upper lobes. Even though high resolution computed tomography (HRCT) scan features are considered characteristic, a histological confirmation is suggested, mainly when the clinical setting is not clearly defined. However, due to non-negligible complications, a surgical lung biopsy is not often recommended. The prognosis is usually poor and currently, the only effective treatment is lung transplantation. METHOD Patients with a multidisciplinary diagnosis of iPPFE or airway-centered fibroelastosis (airway-centered FE), with histological confirmation by transbronchial cryobiopsy, were identified from an ongoing interstitial lung disease registry. Data on patient demographics, HRCT patterns, size and number of biopsies, histology patterns and complications were registered. RESULTS Seven patients were diagnosed with iPPFE and one patient was diagnosed with airway-centered FE. Pneumothorax was documented in three cases, but none of them required a chest tube. No other complications during or after the procedure were observed. CONCLUSION This study suggests that using cryobiopsies in the diagnostics of PPFE and airway-centered FE is safe and effective.

Abstract
Objectives To apply the Delphi exercise with iterative involvement of radiologists and pulmonologists with the aim of defining a structured reporting template for high-resolution computed tomography (HRCT) of patients with fibrosing lung disease (FLD). Methods The writing committee selected the HRCT criteria—the Delphi items—for rating from both radiology panelists (RP) and pulmonology panelists (PP). The Delphi items were first rated by RPs as “essential”, “optional”, or “not relevant”. The items rated “essential” by < 80% of the RP were selected for the PP rating. The format of reporting was rated by both RP and PP. Results A total of 42 RPs and 12 PPs participated to the survey. In both Delphi round 1 and 2, 10/27 (37.7%) items were rated “essential” by more than 80% of RP. The remaining 17/27 (63.3%) items were rated by the PP in round 3, with 2/17 items (11.7%) rated “essential” by the PP. PP proposed additional items for conclusion domain, which were rated by RPs in the fourth round. Poor consensus was observed for the format of reporting. Conclusions This study provides a template for structured report of FLD that features essential items as agreed by expert thoracic radiologists and pulmonologists.

Abstract
AIMS The association between lung cancer and idiopathic pulmonary fibrosis (IPF) is well known, but the significance of this association is poorly understood. Bronchiolar honeycomb cysts have been proposed as possible precursors for the development of carcinoma, but limited evidence in support of this hypothesis is available. The aim of this study was to investigate this hypothesis analysing a series of carcinomas arising in IPF by immunohistochemistry. METHODS AND RESULTS Thirty-three lung carcinomas arising in patients with IPF were analysed with a panel of immunohistochemical markers. The antibodies included those against pneumocyte markers [thyroid transcription factor 1 (TTF1), napsin-A, and surfactant protein A], the goblet cell marker mucin 5AC, markers of basal/squamous cell differentiation [cytokeratin (CK) 5/6 and ΔN-p63], and markers related to enteric differentiation (CDX2, mucin 2, CK20, and villin). A series of 100 consecutive lung adenocarcinomas arising in smokers without IPF were investigated as controls. All carcinomas arising in IPF patients were peripherally located on imaging analysis. The diagnoses were: eight squamous cell carcinomas, 20 adenocarcinomas, three small-cell carcinomas (including one composite small-cell carcinoma and adenocarcinoma), and two large-cell carcinomas. Among adenocarcinomas, a 'pneumocyte' profile (TTF1/napsin-A/SPA1-triple-positive) was observed in seven of 20 (35% versus 84% in non-IPF controls, P = 0.0001). The remaining 13 adenocarcinomas (65%) showed rare histotypes: four invasive mucinous adenocarcinomas (20% in IPF patients versus 1% in non-IPF controls, P = 0.002), seven tumours (35%) that were characterized by variable expression of markers of enteric differentiation, and two tumours (10%) that showed a peculiar basaloid component. CONCLUSIONS The immunohistochemical characterization of carcinomas arising in IPF patients shows striking divergence from that in non-IPF smokers. The prevalence of rare entities showing bronchiole-related markers is in line with the hypothesis that these tumours arise from transformed small airways in honeycomb lung areas where abnormal bronchiolar proliferation takes place.

Abstract
BACKGROUND Transbronchial lung cryobiopsy (TBLC) can be indicated in diffuse parenchymal lung diseases (DPLDs) when a confident noninvasive diagnosis cannot be made. The 2 most relevant complications of TBLC are bleeding and pneumothorax (PTX). The accuracy of chest ultrasonography (US) for the detection of PTX is higher when compared to chest X-ray (CXR) with reference to computed tomography (CT) scan as a gold standard. OBJECTIVE We evaluated the accuracy of chest US in detecting PTX after TBLC in patients with DPLDs. METHODS Patients underwent TBLC during rigid bronchoscopy in deep sedation. Cryobiopsy was performed with fluoroscopic guidance. Three hours later, patients underwent chest US and standard CXR. When there was no concordance between chest US and CXR, chest CT was required. RESULTS Forty-three patients were enrolled into the study. Cryobiopsy was performed in the right lung in 36 (84%) patients. PTX was diagnosed in 10 (23%) patients by CXR. There was complete agreement between radiologists interpreting CXR (k = 1, 95% CI 1). Chest US was positive for PTX in 11 (25%) patients. There was complete agreement between pulmonologists interpreting chest US (k = 1, 95% CI 1). The prevalence of PTX diagnosed by concordance of CXR and chest US was 23% (10/43, 95% CI 11.8-38.7). The sensitivity and specificity of chest US were 90% (95% CI 55.5-99.7) and 94% (95% CI 79.8-99.3), respectively. Moreover, the positive and negative predictive values were 82% (95% CI 48-98) and 97% (95% CI 84-100), respectively. CONCLUSION Chest US is a highly sensitive and specific diagnostic tool for the diagnosis of PTX after TBLC.

Abstract
PURPOSE Pleuroparenchymal fibroelastosis (PPFE) is a rare form of interstitial pneumonia, characterized by elastotic fibrosis involving the pleura and subpleural parenchyma, predominantly in the upper lobes. PPFE can be either idiopathic or secondary and mostly occurs as a late complication of lung or hematopoietic stem cell transplantation (HSCT). The aim of this study was to evaluate the prevalence of secondary forms in transplant recipients. METHODS An expert thoracic radiologist retrospectively reviewed high-resolution computed tomography exams of 700 HSCT recipients and 53 lung transplant recipients from the database of the Radiology Department of S. Orsola-Malpighi Hospital dating back from 2007. For each case that radiologically fulfilled PPFE criteria, the following details were retrieved: clinical characteristics, laboratory and functional data, pathologic findings (obtained from one patient) and metabolic data (obtained from three patients). RESULTS Six cases clinically and radiologically consistent with PPFE were identified: two HSCT recipients (0.28%) and four lung transplant recipients (7.54%). CONCLUSION In this study, PPFE was strongly associated with lung transplants as a late complication, with a prevalence of 7.54%.

Abstract
BACKGROUND Transbronchial lung cryobiopsy is an innovative method of obtaining samples from the parenchyma of patients with diffuse parenchymal lung diseases. However, the technique is not yet standardized, and uncertainty exists about the optimal protocol, including the number of samples, the biopsy size, and the choice of the biopsy site. OBJECTIVES To compare the diagnostic yield and complications of cryobiopsy with different strategies adopted to sample lung tissue (number of samples, biopsy site, and sample size). METHODS We prospectively enrolled 46 patients with suspected diffuse parenchymal lung diseases for the diagnosis of which a biopsy was deemed useful. All patients underwent transbronchial lung cryobiopsy, and they were randomly assigned to group A (4 samples obtained from the same segment) or group B (2 samples obtained from one segment and 2 samples obtained from a different segment of the same lobe). Analysis of the samples was performed sequentially (from the first to the last sample), and pathologists reformulated their histopathologic diagnosis with the addition of each sample. RESULTS The mean diagnostic yield of the procedure combining the 2 groups and performing only the first sampling was 69%. When a second biopsy was performed as well, the mean diagnostic yield improved, but this increase was significant only when the 2 samples were obtained from 2 different segments (96%, group B). CONCLUSIONS This study suggests that the strategy of performing 2 biopsies with a cryoprobe may be associated with an increased diagnostic yield in diffuse parenchymal lung diseases if these samples are obtained from 2 different segments within the same lobe.

Abstract
RATIONALE Angiosarcomas are rare, malignant vascular tumors. PATIENT CONCERNS They represents about 2% of all soft tissue sarcoma, which can often metastasize through the hematogenous route. The radiological features have been analyzed in 4 patients with metastatic angiosarcoma in the chest. DIAGNOSES The main radiologic findings included nodules, cysts, nodules with halo sign, and vascular tree-in-bud. Morphologic features, as observed in the histologic specimen, have been correlated with radiologic appearance. LESSONS Metastatic angiosarcomas to the lung are characterized by a wide variety of radiologic appearances that can be very characteristic. Computed tomographic findings observed include bilateral solid nodules, cystic, and bullous lesions sometimes associated with spontaneous hemopneumothoraces.
