Role of surgery in high-grade neuroendocrine tumors of the lung.

Background: This study aims to evaluate the surgical results for high-grade neuroendocrine carcinomas and to identify factors that influence prognosis.

Methods: Between January 2009 and December 2017, a total of 71 patients (58 males, 13 females; mean age: 62±9.6 years; range, 38 to 78 years) with a high-grade neuroendocrine carcinoma of the lung were retrospectively analyzed.

Behçet's disease presenting with massive hemoptysis related to bronchovascular fistula: A case report.

A 37-year-old male patient was admitted to our hospital with recurrent hemoptysis, 50 mL per day. Thoracic computed tomography showed no pathology responsible for hemoptysis. Bronchoscopy revealed mucosal infiltrations and 2 to 3-mm blotch in the lateral wall of the right lower lobe.

Tracheobronchial Amyloidosis Mimicking Tracheal Tumor.

Tracheobronchial amyloidosis is a rare presentation and accounts for about 1% of benign tumors in this area. The diagnosis of disease is delayed due to nonspecific pulmonary symptoms. Therapeutic approaches are required to control progressive pulmonary symptoms for most of the patients.

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.

Interobserver agreement among histological patterns and diagnosis in lung adenocarcinomas.

Objective: The aim of this study was to investigate the interobserver agreement in determination of the dominant histological pattern and the final diagnosis in lung adenocarcinomas.

Material And Method: A total of 12 patients with a diagnosis of primary lung adenocarcinoma were included in the study. Twelve pathologists from eight study centers were asked first to determine the dominant histological pattern in these cases and then to decide whether the final diagnosis was in situ, minimally invasive or invasive adenocarcinoma.

Squamous cell carcinomas confined to the bronchial wall: the effect of growth patterns.

Background: Squamous cell carcinomas confined to the bronchial wall (SCC-CBW) exhibit two distinct patterns of growth: superficially spreading and endobronchial mass lesions. We examined whether differences exist in the histopathological features and prognosis of SCC-CBW exhibiting different growth patterns.

Materials And Methods: In this study, 37 cases with SCC-CBW were included.

Relationship between lung adenocarcinoma histological subtype and patient prognosis.

Purpose: Lung adenocarcinoma (AC) demonstrates various histological subtypes within the tumour tissue. A panel established jointly by the IASLC, ATS and ERS classified invasive lung ACs based on the predominant histological subtype. We examined the distribution of tumours in lung AC patients according to histological subtype and analysed the effects of this classification on survival.
