Chronic lung allograft dysfunction (CLAD) remains a major hurdle limiting long-term survival post lung transplantation. Given the clinical heterogeneity of CLAD, recently two phenotypes of CLAD have been defined [bronchiolitis obliterans syndrome (BOS) vs. restrictive allograft syndrome (RAS) or restrictive CLAD (rCLAD)]. BOS is characterized by an obstructive pulmonary function, air trapping on CT and obliterative bronchiolitis (OB) on histopathology, while RAS/rCLAD patients show a restrictive pulmonary function, persistent pleuro-parenchymal infiltrates on CT and pleuroparenchymal fibro-elastosis on biopsies...

BACKGROUND: Computed tomography (CT)-guided percutaneous lung fine needle aspiration (FNA) is a convenient method to obtain samples from pulmonary lesions. FNA has a lower rate of complications than the use of a core needle biopsy, but is more difficult for the diagnosis of cytological samples. We use cell block (CB) and immunocytochemistry (ICC) to improve the accuracy of cytological diagnoses based on CT-guided percutaneous lung FNA. METHODS: We collected 526 cytological samples obtained using CT-guided percutaneous lung FNA at Shanghai Pulmonary Hospital from May 2015 to October 2015...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Increased early detection and personalized therapy for lung cancer have coincided with greater use of minimally invasive sampling techniques such as endobronchial ultrasound-guided biopsy (EBUS), endoscopic ultrasound-guided biopsy (EUS), and navigational biopsy, as well as thin needle core biopsies. As many lung cancer patients have late stage disease and other comorbidities that make open surgical procedures hazardous, the least invasive biopsy technique with the highest potential specimen yield is now the preferred first diagnostic study...

OBJECTIVE: To develop a new score (CATH-score) for predicting intra-procedural risk in patients undergoing CT-guided percutaneous needle pulmonary biopsy. PATIENTS AND METHODS: 100 CT-guided lung biopsies performed with a 18 Gauge (G) needle (Pilot Group) were reviewed to analyse patient-, lesion- and procedure-related variables to identify risk factors for procedural complications (pneumothorax and parenchymal bleeding) and diagnosis failure. A scoring system for predicting complications and choosing the right needle (16 G, 18 G, 21 G) was developed using risk factors weighting and prospectively applied to 153 consecutive biopsies (CATH-score Group); complications and diagnostic rates obtained were compared with a group of patients (Control Group) that underwent lung biopsy; in this group of patients the choice of the calliper of the needle was based on the operator experience...

Dyskeratosis congenita (DC) is a rare, inherited, bone marrow failure syndrome caused by premature telomere shortening. The classic mucocutaneous triad of clinical features comprises reticulated skin pigmentation, nail dysplasia, and oral leukoplakia. Multiple somatic features, including bone marrow failure, pulmonary fibrosis, and liver disease, are also common. DC significantly increases the risk for malignant transformation, including myelodysplastic syndrome, acute myeloid leukemia, head and neck squamous cell carcinoma, and anogenital cancer...

Nocardiosis is an infectious disease with wide range of clinical features, which can eventually lead to death. The agent responsible belongs to the genus Nocardia that includes about fifty different species. Nocardiosis occurs mainly in immunocompromised hosts. We report here three cases of disseminated nocardiosis misdiagnosed initially as cerebral metastatic lung cancer. These patients, including two immunocompetent hosts, presented with both pulmonary and cerebral lesions. In all three patients, the diagnosis was based on magnetic resonance imaging with diffusion sequence, apparent diffusion coefficient reconstruction and neurosurgical cerebral biopsies...

We report a case of metastatic pulmonary calcification in a patient with chronic renal failure on hemodialysis and secondary hyperparathyroidism. The diagnosis was made by using a probe-based confocal endomicroscopy which showed specific structures in the lung tissue and was proven by a transbronchial lung biopsy. To the best of our knowledge, this is the first reported case of the confocal endomicroscopy findings in a patient with metastatic pulmonary calcification.

Patient with Pancoast Tumor usually present in advanced stage of the disease which requires chemotherapy and radiotherapy as options of treatment. Histologic confirmation is a key for further treatment of these patients. Normally in bronchoscopy the lesion can't be visualised and in result making biopsy difficult to perform. Transthoracic biopsy through computed tomography poses anatomic difficulties and not always the pulmonary lesion can be reached. We report a case of pancoast tumor in a 68 year old male who presented with left arm pain and upper lobe increased density mass in chest x ray...

Invasive pulmonary aspergillosis (IPA) is a life-threatening lung disease of hematological malignancy or bone marrow transplant patients caused by the ubiquitous environmental fungus Aspergillus fumigatus. Current diagnostic tests for the disease lack sensitivity as well as specificity, and culture of the fungus from invasive lung biopsy, considered the gold standard for IPA detection, is slow and often not possible in critically ill patients. In a previous study, we reported the development of a novel non-invasive procedure for IPA diagnosis based on antibody-guided positron emission tomography and magnetic resonance imaging (immunoPET/MRI) using a [(64)Cu]DOTA-labeled mouse monoclonal antibody (mAb), mJF5, specific to Aspergillus...

In common variable immunodeficiency, lung manifestations are related to different mechanisms: recurrent pneumonias due to encapsulated bacteria responsible for diffuse bronchiectasis, diffuse infiltrative pneumonia with various patterns, and lymphomas, mostly B cell extranodal non-Hodgkin type. The diagnosis relies on significant serum Ig deficiency and the exclusion of any primary or secondary cause. Histopathology may be needed. Immunoglobulin (IgG) replacement is crucial to prevent infections and bronchiectasis...

BACKGROUND AND OBJECTIVE: Chronic exposure to biomass smoke (BS) can significantly compromise pulmonary function and lead to chronic obstructive pulmonary disease (COPD). To determine whether BS exposure induces a unique phenotype of COPD from an early stage, with different physiopathological features compared with COPD associated with smoking (cigarette-smoke (CS) COPD), we assessed the physiopathology of early COPD associated with BS exposure (BS COPD) by incorporating spirometry, high-resolution computed tomography (HRCT) imaging, bronchoscopy and pathological examinations...

Nocardiosis is a rare but severe infection caused by bacteria of the genus nocardia, which belong to the order actinomycetales. If they can affect immunocompetent adult, nocardioses are pathologies affecting the individuals with weakened immune system. Pulmonary involvement is the most common manifestation, its correct management is based on diagnosis, which is often delayed due to non-specific symptoms and inconclusive specimens. We here report two cases of nocardiosis in immunocompetent patients. The first case concerns a 24-year old man with a history of smoking and alcoholism, hospitalized for chest pain and hemoptysis of low abundance evolving for two months, associated with the occurrence of dorsal subcutaneous fistulized abscess...
