BACKGROUND: High serum neuron-specific enolase (NSE) level has been in use as a tumor marker; however, some physicians may ignore NSE levels in serum, especially when the patients are asymptomatic. Here we report a case that a 51 year old female patient with no respiratory symptoms who had a NSE level which increased extremely over three months and was eventually diagnosed small cell lung cancer (SCLC). METHODS: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in right pulmonary hilar enlarged lymph node was performed for diagnosis...

A 45-year-old woman, who had been treated for bronchial asthma, was referred to our hospital with symptoms of dyspnea. Upon examination, we found the right main bronchus to be almost completely occluded by an endobronchial tumor. For the purpose of diagnosis and relieving the dyspnea, we performed a rigid bronchoscopic tumor resection with a high frequency snare. The tumor was pathologically diagnosed as a typical bronchial carcinoid, and a right upper lobectomy and wedge resection of the right main bronchus was carried out 1 month later...

Multiple biomarkers are under evaluation to guide the use of immune checkpoint inhibitors in non-small-cell lung cancer (NSCLC), including programed death ligand 1 (PD-L1) tumor cell staining. We have developed a new approach that accurately quantifies PD-L1 status and identifies multiple mutations by using a single bronchoscopy specimen. A novel molecular marker was identified to detect the presence of malignant cells in radial endobronchial ultrasound bronchial brushings from NSCLC (n = 15) and benign (n = 13) nodules by quantitative real-time RT-PCR (RT-qPCR)...

BACKGROUND: Pulmonary carcinoids are included in the group of neuroendocrine tumors (NET) and derive from pulmonary neuroendocrine cells. The incidence of these tumors is increasing, but disease awareness remains low among clinicians. The synchronous presentation of lung cancer and mycobacterial infection is well known but the combination of pulmonary carcinoid and mycobacterial infection is rare. CASE PRESENTATION: We treated a 45-year-old female who presented with recurrent pneumonia...

Bronchoscopy cryoprobes are used for palliative treatment of endobronchial obstructions caused by tumors and removal of granulation tissue or foreign bodies. Currently this technology is also used for diagnosis of diffuse interstitial lung disease (ILD). The multidisciplinary team that establishes the clinical, radiological and histopathological correlation in ILD, decides about performing a surgical lung biopsy when the characteristics of the interstitial disease are not similar to Idiopathic Pulmonary Fibrosis (IPF)...

Lymphoproliferative disorders can occur in patients with autoimmune disorders who undergo long-term methotrexate therapy (MTX-LPD). Although the manifestations of MTX-LPD are diverse, little attention is paid to endobronchial involvement. We herein describe two patients with MTX-LPD who presented with parenchymal pulmonary tumors and endobronchial involvement of LPD; one had lymphomatoid gramulomatosis and the other LPD. The patients had no tumors adjacent to the endobronchial lesions. The endobronchial findings included multiple protruded mucosal lesions covered with white material, which was pathologically consistent with LPD...

Endobronchial metastasis from extrapulmonary solid tumors is rare, and endobronchial metastasis from the prostate is even more unusual. An 80-year-old patient presented with significant dyspnea secondary to metastatic stromal cell sarcoma of the prostate, which occluded the right main bronchus. The tumor, causing complete collapse of the right lung, was found on computed tomography and confirmed by bronchoscopy. We successfully excised the lesion using cryotherapy, with immediate resolution of symptoms and radiological lung reexpansion...

Benign central airway obstruction (CAO) is responsible for significant morbidity due to dyspnea and impaired quality of life. While iatrogenic causes, including stenosis after endotracheal intubation, tracheostomy tube placement, and surgery, account for the majority of cases of benign CAO, there are a multitude of other causes including infections, inflammatory disorders, extrinsic compression, benign endobronchial tumors, and tracheobronchomalacia. The approach to management depends on the underlying process responsible for the disorder and may include systemic therapy, endoscopic therapy, and surgery...

BACKGROUND Lung mucoepidermoid carcinoma is a form of non-small cell lung carcinoma that originates from the submucosal glands of the tracheobronchial tree; it is rare and causes 0.1% to 0.2% of lung malignancies. In this article, we report on an occurrence of this condition in an 81-year-old male, which is rare occurrence in this age group. In this case, we found a history of smoking and asbestos exposure which might suggest that exposure to both of these factors can possibly increase the risk for this malignancy...

Pulmonary artery intimal sarcoma is a rare aggressive intraluminal tumor often misdiagnosed as acute or chronic pulmonary thromboembolism due to its clinical presentation and radiological findings. Thus early diagnosis is very crucial and may improve patient outcome. There is limited literature on diagnosis of pulmonary artery sarcoma by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Herein, we report a case of mass-like lesion in the PA diagnosed on cytological material obtained by EBUS-TBNA with rapid on-site evaluation (ROSE)...
