Clear cell tumor of the lung is a rare benign tumor. The current study presents the case of a 60-yearold man who had an abnormal pulmonary nodule at chest x-ray. A computed tomography (CT) scan of the patient’s lung showed a 2x2x1.5 cm solitary nodule in the anterior segment of the left upper lobe. The patient underwent a lobectomy for the tumor. The pathologic examination revealed sheets of large round or polygonal cells with clear cytoplasm and immunoreactive positivity for HMB-45 and NSE. Investigation with PET/CT scan showed no evidence of renal disease. This case provides a very rare example of a solitary pulmonary nodule as clear cell carcinoma. The patient showed no evidence of recurrence or metastasis after three years postoperatively.

Objective: To report a case of Churg-Strauss syndrome who had asthma and allergic rhinitis treated with montelukast. Clinical Presentation and Intervention: A nonsmoking 59-year-old woman presented with fever, hemoptysis and dyspnea. Past medical history included allergic rhinitis and asthma which were diagnosed 18 years ago. The asthma was treated successfully with inhaled salmeterol and beclamethasone. She also received montelukast (10 mg/day) for 3 years. Although her chest X-ray was normal a week earlier, she had widespread bilateral pulmonary infiltrates on admission. She had leukocytosis (12.5 × 109/l) with eosinophilia (15.6%). Her total IgE count was 550 U/ml. Testing for protoplasmic-staining antineutrophil cytoplasmic antibodies was positive. Bronchoalveolar lavage could not be performed due to bronchospasm and severe hypoxemia; however, mucosal biopsies were obtained, which revealed eosinophil leukocytes in the lumen and walls of small vessels. She was diagnosed to have Churg-Strauss syndrome and had remarkable clinical improvement on day 5 with high-dose of oral prednisolone (50 mg/day). Radiological improvement was detected at the end of the second week. Conclusion: This case shows the importance of being aware that leukotriene receptor antagonists could cause Churg-Strauss syndrome, in spite of the uncertainty about its mechanism.

Background/aim: Sex-related differences have not been thoroughly explored in chronic obstructive pulmonary disease (COPD). We aimed to evaluate possible sex-related differences in COPD Assessment Test (CAT) scores of COPD patients with or without significant anxiety and/or depression. Materials and methods: Stable COPD patients were prospectively enrolled in the study between July 2013 and April 2014. Levels of anxiety, depression, dyspnea, and health-related quality of life parameters were assessed using specific questionnaires, including the CAT and others. Demographic and clinical data were recorded and physiological tests were performed. All the data were compared to determine any sex-related differences. Results: A total of 128 COPD patients (86 men, 42 women, mean age: 60.5 ± 9.3 years) were included. The women were significantly younger and had lower pack-years of cigarette smoking, and higher biomass smoke exposure, but displayed similarly severe COPD as compared to men. Beck anxiety (13.5-11) and Beck depression (15-11) inventory results were significantly higher in women than men (P = 0.04, P = 0.01). No statistically significant difference was found between the sexes in terms of CAT score, Modified Medical Research Council score, or COPD stage parameters (P > 0.05). Conclusion: Female patients have higher levels of depression and anxiety scores but present the same CAT scores related to COPD severity as compared to men.

Activation of coagulation and fibrinolysis is frequently encountered among cancer patients. Such tumors are supposed to be associated with higher risk of invasion, metastases and eventually worse outcome. The aim of this study is to explore the prognostic value of blood coagulation tests for lung cancer patients.Between 2009 and 2012, 72 newly diagnosed patients with lung cancer and 40 healthy subjects as control group were included in this prospective study. Patients were staged according to the seventh edition of the tumor, node, metastasis (TNM) classification. The treatment responses of patients were evaluated according to the World Health Organization (WHO) criteria. We measured plasma D-dimer level, activated partial thromboplastin time (APTT), prothrombin time (PT), international normalized ratio (INR), lactate dehhydrogenase (LDH), hemoglobin (Hb), platelet (Plt), white blood cells (WBC) count before, during and after chemotherapy. We investigated association of the results with stage and histologic type of the disease, as well as with response to therapy and survival in lung cancer patients.The median D-dimer, PT and INR levels of the patients with lung cancer were significantly higher than in the control group (P = 0,000). D-dimer, APTT, PT, INR, LDH levels after four cycles of treatment were significantly lower in responders than in nonresponders (P = 0,000). Plasma D-dimer levels were evaluated according to histopathological type and stage of diseases; D-dimer level was found significantly higher in metastatic disease (P 0,5) and significantly lower in small cell lung cancer (SCLC) (P 0,05). The mean follow-up was 574,14 ± 463,48 days. The mean survival was 750,866 ± 74,857 days (95% CI: 604,147 - 897,586). After second and fourth cycles of treatment, the plasma D-dimer, APTT, and LDH levels were higher in mortality group than in survival group (P = 0,000). After four cycles of treatment, the mean survival of the patients with serum D-dimer level above and below 1900 ng/mL was found to be significantly different (P = 0,000).The results suggest that determination of D-dimer plasma levels that is an inexpensive, easy and non invasive method may be useful in predicting clinical outcome, survival and treatment response of patients with lung cancer.

Pulmonary nodular lymphoid hyperplasia (NLH) is defined as reactive lymphoid proliferation forming solitary or multiple nodules or localized infiltrates localized in the lungs. Radiological presentations are generally solitary or multiple nodules, but air bronchograms and ground glass attenuation may be present. Patients mostly asymptomatic and the lesions were detected coincidentally on routine chest X-rays. We present a case of NLH with cavitary lesion arising in the lung of a 61 year-old man who admitted with cough and massive hemoptysis. The lesion had positive fluorodeoxyglucose (FDG) uptake. To our knowledge, this is the only patient reported in the literature presenting with massive hemoptysis and a cavitary lesion with positive FDG uptake.

Hydatid disease is endemic in Turkey. Echinococcus granulosus causes cystic echinococcosis mostly in the liver and lung. Although pulmonary hydatid cysts can be diagnosed by clinical and radiological findings, atypical or complicated lung lesions may be misdiagnosed. In the present study, three cases with hemoptysis and atypical lung lesions were diagnosed and treated as lung cancer or tuberculosis based on the clinical and laboratory findings along with the imaging data and fiberoptic bronchoscopy evaluation. Eventually, pathological examination of the bronchoscopic biopsy material confirmed the definitive diagnosis as pulmonary hydatidosis. The three patients presented herein emphasize the importance of considering pulmonary hydatid disease in the definitive diagnosis of atypical lung lesions such as bronchial carcinoma in echinococcosis endemic areas.

Brain metastases are frequent features during the course of patients with lung carcinoma. The aim of this study was to investigate prognostic factors for patients with brain metastasis from lung cancer. Eighty-eight patients with brain metastasis from lung cancer were enrolled in the study. Eighty-two of cases were male, six were female and the mean age was 57.5 +/- 10.4 years. The most common symptoms were headache (32.9%) and dizziness (32.9%). Fifty-two (59.1%) patients had solitary brain metastasis and the most frequent metastasing site was parietal lobe (34.1%). The median survival times were 3 months after diagnosis of lung carcinoma and 1.5 months after diagnosis of brain metastasis. Although the absence of brain metastasis at the moment of diagnosis, metachronous metastasis, central localization of the tumour, chemotherapy administration and surgical treatment of brain metastasis are good prognostic factors affecting survival after the diagnosis of lung carcinoma, the positive factors affecting survival after brain metastasis are central localization of tumour, chemotherapy administration and surgical treatment of brain metastasis. In conclusion, performing the combination of cranial radiotherapy, chemotherapy, surgical therapy and supporting therapy should be evaluated in all appropriate patients with brain metastasis from lung cancer.

A 21-year-old man was admitted with cough, facial swelling, and breathlessness. Routine laboratory tests were normal. Computed tomographic (CT) scanning demonstrated a mass with diffuse mediastinal involvement and bilateral pleural effusion. The mass extended from the thoracic inlet to the level of the inferior pulmonary vein (Figure 1). Because of superior vena cava syndrome and dyspnea, he was initially treated with oxygen, high-dose dexamethasone, and bronchodilation. Pleural fluid analysis showed an exudae and benign cytology. The mediastinal tumor had nearly completely disappeared 6 days later when a CT was repeated (Figure 2) for a core biopsy. Because of the dramatic tumor shrinkage, biopsy was deferred, and the patient was dismissed. One month later, he was readmitted, with CT revealing an increase in mediastinal tumor (Figure 3). Pathological evaluation of the CT-guided core biopsy revealed lymphoblastic lymphoma, immunoreactive for TdT, CD 3, CD-45
