Asymptomatic endoalveolar hemorrhage in a young male

We describe the case of a young male affected by granulomatosis with polyangiitis presenting with non-specific complaints and complicated by the occurrence of a diffuse endoalveolar hemorrhage characterized by atypical clinical and radiological features. The importance of a rapid and aggressive diagnostic and therapeutic approach has to be strongly underlined. Available data regarding prevalence, clinical and radiological characteristics and treatment of this uncommon manifestation have also been hereby reviewed

Diagnostic Accuracy of Slow-Capillary Endobronchial Ultrasound Needle Aspiration in Determining PD-L1 Expression in Non-Small Cell Lung Cancer

Introduction: The role of EBUS-TBNA in the diagnosis and staging of lung cancer is well established. EBUS-TBNA can be performed using different aspiration techniques. The most common aspiration technique is known as "suction". One alternative to the suction technique is the slow-pull capillary aspiration. To the best of our knowledge, no studies have assessed the diagnostic yield of slow-pull capillary EBUS-TBNA in PD-L1 amplification assessment in NSCLC. Herein, we conducted a single-centre retrospective study to establish the diagnostic yield of slow-pull capillary EBUS-TBNA in terms of PD-L1 in patients with NSCLC and hilar/mediastinal lymphadenopathies subsequent to NSCLC. Materials and Methods: Patients with hilar and/or mediastinal lymph node (LN) NSCLC metastasis, diagnosed by EBUS-TBNA between January 2021 and April 2022 at Pulmonology Unit of "Ospedali Riuniti di Ancona" (Ancona, Italy) were enrolled. We evaluated patient characteristics, including demographic information, CT scan/ FDG-PET features and final histological diagnoses, including PD-L1 assessment. Results: A total of 174 patients underwent EBUS-TBNA for diagnosis of hilar/mediastinal lymphadenopathies between January 2021 and April 2022 in the Interventional Pulmonology Unit of the "Ospedali Riuniti di Ancona". Slow-pull capillary aspiration was adopted in 60 patients (34.5%), and in 30/60 patients (50.0%) NSCLC was diagnosed. EBUS-TBNA with slow-pull capillary aspiration provided adequate sampling for molecular biology and PD-L1 testing in 96.7% of patients (29/30); in 15/29 (51.7%) samples with more than 1000 viable cells/HPF were identified, whereas in 14/29 (48.3%) samples contained 101-1000 viable cells/HPF. Conclusion: These retrospective study shows that slow-pull capillary aspiration carries an excellent diagnostic accuracy, almost equal to that one reported in literature, supporting its use in EBUS-TBNA for PD-L1 testing in NSCLC

Urothelial and incidental prostate carcinoma in prostates from cystoprostatectomies for bladder cancer: is there a relationship between urothelial and prostate cancer?

To determine the incidence and features of urothelial carcinoma (UC) involving the prostate (UCP) and of prostate adenocarcinoma (PA) in radical cystoprostatectomy (RCP) for bladder cancer

Fibroelastosi pleuroparenchimale familiare diagnosticata mediante criobiopsia polmonare

Idiopathic pleuroparenchymal fibroelastosis (PPFE), recently included in the updated international classification of idiopathic interstitial pneumonias (IIPs), is a rare condition characterized by pleural fibrosis and subadjacent parenchymal fibroelastosis, with an upper-zone predominance. It might also occur in the context of familial IIPs or be associated to pre-existing underlying conditions, such as recurrent infections, transplantations, previous chemotherapies, and connective tissue diseases. Although a definite consensus regarding the diagnostic criteria has yet to be established, a proper diagnostic work-up necessarily requires the identification of morphological features consistent with PPFE. However, surgical lung biopsy is characterized by appreciable costs and risks, and many subjects cannot undergo the procedure because of an increased risk of perioperative morbidity and mortality, due to advanced age, severity of disease, and comorbidities. In this context, transbronchial lung criobiopsy has been recently proposed as a valuable alternative tool for the histopathologic assessment of diffuse parenchymal lung diseases, showing a high diagnostic yield with an excellent safety profile. Here, we report a case of a young woman with familial history of idiopathic pulmonary fibrosis and rheumatoid arthritis, diagnosed with PPFE through transbronchial lung criobiopsy
