BACKGROUND: In advanced non-small cell lung cancer (NSCLC), small biopsy specimens from endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are often the only available material from cancer tissue for the analysis of programmed death ligand-1 (PD-L1) expression. We aim to assess the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PD-L1 expression at ≥1% and ≥50% on EBUS-TBNA samples compared with their corresponding surgically resected tumor...

A 31-year-old woman presented with progressive breathlessness since 1 year. Flexible bronchoscopy revealed a vascular tumor completely occluding the right main bronchus. A diagnosis of primary endobronchial myxoma was made. Tumor debulking was performed using rigid bronchoscopy. This enabled right lower lobectomy. A literature search yielded 12 cases of primary pulmonary myxoma, and only 2 previous reports of endobronchial myxoma. Most tumors were incidentally detected and were cured surgically. Endobronchial myxomas are rare and are usually asymptomatic...

Background: Primary endobronchial smooth muscle tumors (SMTs), which are extremely rare, include endobronchial leiomyomas and leiomyosarcomas. Clinically, SMTs present with signs and symptoms of bronchial obstruction, and lack specific radiological findings. Thus, histopathological examination is required for accurate diagnosis as well as for tumor grading. We examined the histomorphological and immunohistochemical features of endobronchial SMTs and highlighted pitfalls in diagnosis, particularly when using small biopsies...

BACKGROUND: Pulmonary epithelial-myoepithelial carcinoma (P-EMC) is a rare subset of salivary gland-type tumors of the lung. Because of its rarity and unproven malignant potential, the optimal therapy for P-EMC has not been defined. Here, we report a typical case of P-EMC and a review of the literature to consider appropriate treatment. CASE PRESENTATION: A 54-year-old woman presented with an abnormal lung shadow on a routine chest X-ray. A chest computed tomography (CT) scan verified an 18-mm endobronchial nodule on the middle lobe...

Central airway obstruction, a frequently encountered emergency, is usually associated with blood clots, tumors, foreign bodies or mucus plugs. Airway obstruction due to blood clots can be seen as a complication of lung malignancies, infections, bronchiectasis, arteriovenous malformations or pulmonary infarction. In patients with long standing blood clots, the thrombus gets organized and firmly adherent to the airway. The diagnosis is often misleading as these clots mimic tumors clinically and on imaging. Hemoptysis is the most common presenting symptom though many patients can be asymptomatic...

Carcinoid tumor is a neuroendocrine tumor that can arise in the bronchial tree and can be hypervascular. Here we describe a case of bronchial carcinoid tumor in a 34-year-old previously healthy male who presented with hemoptysis and right lung mass. Inspection bronchoscopy revealed bronchus intermedius endobronchial lesion and was complicated by urgent intubation and placement of endobronchial blocker for massive hemorrhage. Subsequent angiography with embolization of the bronchial artery supplying the mass resulted in control of bleeding...

We report a case of a huge solitary non-endobronchial pulmonary tumor in a 76-year-old male smoker. The tumor measured 11 × 10 × 8 cm. It was ill-defined, and it was located periphery of the right lower lobe with the subpleural cystic spaces. He underwent right lower lobectomy with mediastinal lymph node dissection and is free from tumor 30 months after surgery. Microscopically, it was composed of a proliferation of squamous and ciliated columnar epithelial cells with a few mucous cells. These cells were arranged in a papillary growth fashion extending along the fibrously thickened alveolar septa together with metaplastic bronchiolar and squamous epithelia displaying an usual interstitial pneumonia-pattern...

Esophageal lyomyoma are rare benign tumors of the esophagus and they remain usually undiagnosed until local compression symptoms occur in the esophagus. Gastroscopy or esophageal ultrasonography (EUS) are usually the methods of choice for diagnosis. Moreover; surgery is the solution for this entity. In our case we present diagnosis of esophageal lyomyoma using convex probe endobronchial ultrasound (EBUS) with a fine needle aspiration of 22G.

Ovarian cancer is the seventh most common cancer in women and the eighth most common cause of cancer death in the world with an overall 5-year survival rate of <50%. (1) The most common age of presentation is at the perimenopausal age group and two-thirds of them present with advanced stage of disease. (2) Thoracic metastases occur in up to 50% of patients. Pleural effusion is the most common presentation of thoracic metastases in these patients, whereas pulmonary parenchymal metastases, lymphangitis, and nodal involvement are less commonly reported...

BACKGROUND: Metastasis of breast cancer to mediastinal lymph nodes is common and biopsy of suspicious lesions can have important diagnostic, prognostic, and therapeutic implications, particularly with respect to tumor receptor status. Our aim was to show that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can be used for the diagnosis of metastatic breast cancer and demonstrate reliable receptor evaluation that can result in change of therapy. METHODS: A retrospective review of consecutive adult patients undergoing EBUS-TBNA from May 2007 to September 2012 was performed...

BACKGROUND: Stereotactic body radiotherapy (SBRT) had become a therapeutic modality in patients with primary tumors, locally recurrent as well as oligometastasis involving the lung. Some modalities of SBRT require fiducial marker (FM) for dynamic tumor tracking. Previous studies have focused on evaluating bronchoscopic-guided FM placement for peripheral lung nodules. We describe the safety and feasibility of placing FM using real-time convex probe endobronchial ultrasound (CP-EBUS) for SBRT in patients with centrally located hilar/mediastinal masses or lymph nodes...

OBJECTIVE: PD-L1 immunohistochemistry (IHC) is essential in patients of advanced non-small-cell-lung cancer (NSCLC) to determine eligibility for immunotherapy. PD-L1 IHC assays have been clinically validated only on FFPE tissue; however, lung cancer is frequently diagnosed on cytology. PD-L1 immunocytochemistry (ICC) has shown high concordance of immunoexpression between cytology samples and paired small biopsies. Feasibility of liquid-based cytology (LBC) smears for PD-L1 ICC has not been analyzed previously...

Evaluation of mediastinal lymphadenopathy in patients with a previous diagnosis of renal cell carcinoma (RCC) is critical for the determination of further treatment. A minimally invasive method of cytology sampling of mediastinal lymph nodes using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a useful tool in diagnosis. Between January 2010 and April 2018, we performed 1744 EBUS-TBNA studies of mediastinal and hilar lymph nodes for a variety of clinical indications including mediastinal malignancy...
