To Investigate the Effect of Targeted Overdilation in Balloon-Expandable Stents.

Purpose: Balloon-expandable stents are commonly used for the treatment of tracheobronchial strictures. We routinely perform targeted overdilation of these stents 1-2mm on initial deployment to prevent stent migration or allow foreshortening to target airway caliber; however, specific data on the effect of targeted overdilation is unknown.

Patients And Methods: We used three iCAST stents (6×22mm, 7×22mm, and 10×38mm) to perform the study.

Cytomorphologic features of malignant solitary fibrous tumor with mediastinal involvement sampled by endoscopic and endobronchial ultrasound-guided fine-needle aspiration: A comparison of two cases.

Solitary fibrous tumor (SFT) is an uncommon fibroblastic neoplasm with considerable risk of local recurrence. SFT is histologically characterized by bland spindled-to-epithelioid cells in alternating hyper- and hypocellular zones, a "patternless pattern," ectatic "staghorn" vessels with variable edematous perivascular stroma, and thick ropey collagen. Cytologically, smears are variably cellular with spindled-to-epithelioid cells with oval nuclei, wispy cytoplasm, multiple inconspicuous nucleoli, and occasional nuclear pseudoinclusions.

Results of bronchoscopic excision in typical carcinoid tumors of the lung in Turkey.

Aim Carcinoid tumors of the lung are the tumors originating from the neuroendocrine cells. Surgical excision remains the gold standard for the treatment. Treatment with interventional bronchoscopic excision has also been reported as an alternative option in typical carcinoid tumors of the lung.

Crohn's disease-associated interstitial lung disease mimicking sarcoidosis: a case report and review of the literature.

Respiratory involvement in Crohn's disease (CD) is a rare manifestation known to involve the large and small airways, lung parenchyma, and pleura. The clinical presentation is nonspecific, and diagnostic tests can mimic other pulmonary diseases, posing a diagnostic challenge and delay in treatment. We report a case of a 60-year-old female with a history of CD and psoriatic arthritis who presented with dyspnea, fever, and cough with abnormal radiological findings.

Diagnosis of Pulmonary Hydatid Cyst by Bronchoscopy.

Hydatid cyst is a parasitic infestation caused by Echinococcus granulosus. Lungs are the second most common site of involvement after liver. The diagnosis of complicated pulmonary hydatid cysts may not be easy because hydatid cyst disease mimics tuberculosis, lung cancer, empyema, or abscess.

Pulmonary Neuroendocrine Tumors: Part I. Spectrum and Characteristics of Tumors.

Pulmonary neuroendocrine tumors arise from Kulchitzky cells of the bronchial mucosa and include typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell lung cancer. These tumors have a variable growth rate that determines their presentation and prognosis. Typical carcinoid has the lowest growth rate and better prognosis; in contrast, small cell lung cancer is an aggressive tumor with a very poor prognosis.
