Two benign appearing endobronchial soft tissue lesions in two young patients (ages 33 and 26) were incompletely excised to conserve normal lung. Both tumors recurred four and seven years later. The first tumor had abundant small vessels in a myxomatous background (angiomyxoma); myofibroblasts formed the invasive component of the second tumor. To the best of our knowledge these two types of tumo...

We report a very rare case of primary endobronchial peripheral T-cell lymphoma (PTCL) not otherwise specified (NOS), which presented as an endobronchial tumor obstructing the main airway. An 81-year-old man was referred to our hospital for a 1-month history of productive cough and wheeze. Computed tomography revealed chronic pyothorax with calcified foci in the right lung and a mass inside the ...

Neurilemmomas are relatively uncommon, slowly growing tumors which originate from Schwann cells. Intrathoracic neurilemmomas often occur in the chest wall and posterior mediastinum, but endobronchial neurilemmomas are exceedingly rare. These tumors in trachea or bronchus are usually detected by radiologic examinations, mostly computed tomography scan of chest. An 88-year-old man was admitted fo...

Although endobronchial hamartoma is a rare benign tumor, most patients with endobronchial hamartoma have respiratory symptoms such as obstructive pneumonia, hemoptysis, cough, or dyspnea due to bronchial obstruction. It can cause irreversible post-obstructive pulmonary destruction, thus early diagnosis and treatment is very important. Recently, there have been cases of neodymium-doped yttrium a...

This new guideline covers the rapidly advancing field of interventional bronchoscopy using flexible bronchoscopy. It includes the use of more complex diagnostic procedures such as endobronchial ultrasound, interventions for the relief of central airway obstruction due to malignancy and the recent development of endobronchial therapies for chronic obstructive pulmonary disease and asthma. The gu...

Tracheobronchial amyloidosis is one of many causes of endobronchial stenosis and nodularity, the concrete diagnosis of which currently requires the finding of apple-green birefringence from endobronchial biopsies. Bronchoscopic probe-based confocal endomicroscopy (pCLE) is a novel optical biopsy technique which provides real-time images of the lattice structure of the bronchial basement memRece...

AIM to determine the effectiveness of endobronchial valve placement as treatment of emphysema compared to medical care. METHODS literature searching regarding comparison of endobronchial valve and medical care as treatment of emphysema on PubMed database. The quality of the literatures found was appraised by using critical appraisal sheet from Center of Evidence-Based Medicine, University of ...

We recently identified a DNA copy number aberration (CNA)-based classifier, including changes at 3p26.3-p11.1, 3q26.2-29, and 6p25.3-24.3, as a risk predictor for cancer in individuals presenting with endobronchial squamous metaplasia. The current study was set out to validate the prediction accuracy of this classifier in an independent series of endobronchial squamous metaplastic and dysplasti...

Herpes simplex virus (HSV) causes tracheobronchitis and pneumonitis; however, to date, there has only been one report of an endobronchial mass caused by HSV type II. This case study describes a 68-yr-old female with severe kyphoscoliosis who was intubated for acute on chronic hypercapnic respiratory failure and developed blood-tinged endotracheal secretions. Fibreoptic bronchoscopy demonstrated...
