Background: Although studies suggest a deficiency in stem cell numbers in chronic airway diseases such as chronic obstructive pulmonary disease (COPD), the role of bronchial epithelial progenitor/stem (P/S) cells is not clear. The objectives of this study were to investigate expression of progenitor/stem (P/S) cell markers, cytokeratin (CK) 5, CK14 and p63 in bronchial epithelial explants and cell cultures obtained from smokers with and without COPD following multiple outgrowths, and to study this effect on bronchial epithelial cell (BEC) proliferation.
Methods: Bronchial epithelial explants were dissected from lung explants and cultured on coverslips.

Total of 129 cases, consisting of 68 cases of malignant pleural mesothelioma (51 epitheloid, 12 biphasic, and 5 sarcomatoid type) and 61 cases of pulmonary adenocarcinoma were examined and stained with monoclonal Caveolin-1. Caveolin 1 expression with a membranous and /or cytoplasmic pattern was detected only in 32.

Pulmonary mucous gland adenomas are rare benign tumors, which need to be differentiated from malign lung masses. The differential diagnosis is of particular importance for those arising from lung parenchyma in atypical locations. In this article, we report a 70-year-old male patient, who had complaints of cough and expectoration for almost two years.

Background: This study aims to investigate the prognostic factors that affect survival rates and durations in patients with T3 non-small cell lung cancer who underwent surgery.
Methods: A total of 129 patients with T3 n on-small c ell l ung c ancer (125 males, 4 females; mean age 60±9.3 years; range 23 to 80 years) who were performed surgery in our clinic between January 1997 and December 2013 were evaluated retrospectively in terms of age, gender, type of resection, tumor histopathology, tumor, node and metastasis staging, lymph node invasion, chemotherapy and radiotherapy, and recurrence.
Background/aim: For the early stage of nonsmall-cell lung cancer, surgical resection provides the best survival, but the surgical risk generally increases with age because of the increased prevalence of comorbidities, especially cardiovascular disorders. The aim of this study was to compare survival and mortality rates of two groups with different ages, younger and older than 70 years, who went curative resection for nonsmall-cell lung cancer.
Materials And Methods: We analyzed the patients who underwent curative lung cancer surgery in the Department of Thoracic Surgery of Gaziantep University Research Hospital between January 1997 and November 2014.
Objective: To emphasize the importance of a careful clinical evaluation to prevent unnecessary interventions and treatments.
Clinical Presentation And Intervention: A 76-year-old female patient had been diagnosed with asthma during previous admissions to different hospitals. She had also undergone fiberoptic bronchoscopy (FOB) on 2 occasions for evaluation of right middle lobe atelectasis observed on computed tomography.
A 47-year-old man was referred for assessment of bilateral lymph node enlargement identified on a routine chest radiograph. Positron emission tomography showed high standardized uptake values (SUVmax: 20.5) in right supraclavicular, right intercostal, and multiple mediastinal lymph nodes.

Objective: To assess the discrepancies that prevailed among the members of the Head and Neck Pathology Working Group in Turkey in diagnosing salivary gland tumors, classified primarily according to myoepithelial origin, by utilizing telepathology.
Study Design: At least 4 representative images were obtained from each case of a total of 47 salivary gland tumors, and these were studied by 14 participants. The tumors examined were classified into 2 categories under behavior as malignant or benign, and also grouped into 2 categories under differentiation: those showing and those not showing myoepithelial differentiation.
Background: We analyzed the relationship between matrix metalloproteinase (MMP)-2, -7, and -13 gene expression and polymorphisms and disease susceptibility and prognosis in patients who had undergone surgery for non-small-cell lung cancers.
Materials And Methods: The study group consisted of 132 patients who had undergone radical surgery for non-small-cell lung cancers. The control group consisted of 80 healthy volunteers.
Pleomorphic adenoma is the most common benign tumor of the salivary glands, mainly arising from major salivary glands such as parotis and submandibular gland. In rare cases, however, pleomorphic adenoma presents in various unusual sites such as the nasal cavity, paranasal sinuses, hypopharynx, pharynx, larynx, trachea and lacrimal glands. We present a rare case of 80-year-old woman with pleomorphic adenoma of the nasal cavity.

In this study, we compared the effects of iloprost and diltiazem on vasospasm.
Methods: Seventy patients who underwent CABG with the RA were randomized into 2 groups, and the vasodilator effects of iloprost and diltiazem were studied prospectively.
Diffuse alveolar haemorrhage (DAH) is indicated by the presence of red blood cells, fibrin and haemosiderin deposits in the lung parenchyma. We present a case of DAH in a 25-year-old male following 5-nitroimidazole treatment. The first episode of haemoptysis occurred following metronidazole treatment 10 months previously.

We aimed to find out whether or not mediastinoscopic frozen section analysis was (i) a reliable tool when deciding to continue resection in lung cancer patients and (ii) reliable in diagnosing mediastinal masses.
Methods: One-hundred and thirty-six patients undergoing mediastinoscopy were enrolled in this study.
