Although interferon has not been classified in the pathogenesis of sarcoidosis, it may rarely lead to this disease during treatment of chronic hepatitis C. The case of a 36-year-old woman with chronic hepatitis C who developed sarcoidosis within 10 weeks of treatment with recombinant interferon-alpha2a and ribavirin is described and all seven similar cases(More)
AIMS The differential diagnosis of malignant mesothelioma (MM) from benign mesothelial lesions (BML) based on histopathological criteria is sometimes not satisfying and causes diagnostic problems for histopathologists. We aimed to investigate whether the immunohistochemically determined cell proliferation rate and telomerase activity, using Ki-67 and human(More)
An 8.5-year-old girl who presented with chronic cough and hemoptysis underwent a CT scan of the chest showing diffuse mediastinal and parenchymal infiltration and pleural effusion, and laboratory findings showed disseminated intravascular coagulation. Disseminated lymphangiomatosis was diagnosed after an open-lung biopsy. She was treated by systemic(More)
Extracranial metastases from meningioma are very rare and among those the lungs are the most common metastatic site. In the literature, pulmonary metastases of meningiomas have been emphasized on their rarity, non-specific imaging findings, and cytologic features. Some definitive MR imaging features of intracranial meningiomas have been described. However,(More)
BACKGROUND AND AIMS The aim of this study was to assess the diagnostic value of image guided percutaneous fine needle aspiration (FNA) biopsy in equivocal mediastinal masses. PATIENTS Sixty-six patients with an equivocal mediastinal mass who underwent FNA biopsy between 1993 and 2003 were eligible for final analysis. The cytological and definitive(More)
PURPOSE The aim of this study was to evaluate the efficacy of PET imaging and compare it with the performance of CT in mediastinal and hilar lymph node staging in potentially operable non-small cell lung cancer (NSCLC). METHODS Fifty-nine patients with potentially resectable NSCLC who underwent preoperative PET and CT imaging were enrolled into this(More)
INTRODUCTION Primitive neuroectodermal tumors (PNETs) are rare, rapidly progressive, small- round cell tumors with a poor prognosis despite multimodal therapy, including surgery and chemoradiotherapy. The treatment of choice was unknown since no clinical series with surgical therapy had been reported. We evaluated the impact of multimodal treatment in(More)
BACKGROUND Some cellular and soluble markers of inflammation in induced sputum have been used for studying airway inflammation in asthma. The aim of this study was to assess the usefulness of systemic inflammation marker serum amyloid A (SAA) in blood and induced sputum to monitor the airway inflammation in asthmatic patients. METHOD Seventeen non-smokers(More)
OBJECTIVE Removing or sampling lymph nodes from the bilateral paratracheal area through a left thoracotomy is not a standard procedure in patients with lung cancer. The aim of this study was to evaluate the feasibility of a technique without ductus arteriosus division and mobilization of the aortic arch and to compare the number of lymph nodes resected in(More)
