BACKGROUND Lung cancer remains the leading cause of cancer death in the world. In Iran, lung cancer is one of the five leading tumours and its incidence has been increasing steadily in both men and women. There is a paucity of data from Iran on risk factors for lung cancer. We evaluated environmental risk factors for lung cancer in a case-control study in(More)
BACKGROUND This study was conducted to determine the antimicrobial susceptibility patterns among common pathogens in the intensive care unit (ICU) of a university hospital in Iran between 2006 and 2009. METHODS The isolates cultured in appropriate media and antimicrobial susceptibility were determined by disk diffusion tests according to the guidelines of(More)
Primary immunodeficiencies (PIDs) are not solely diseases of childhood. We describe the clinical presentation and outcome for 55 adult patients with previously unrecognized PIDs. This series provides unique data regarding PIDs presenting in adulthood, and serves as a timely reminder that physicians must consider the diagnosis of PIDs in their adult(More)
A 24-year-old man presented to our center with a huge goiter compressing his airway. He had a previous diagnosis of Langerhans cell histiocytosis (LCH) of the lung. Core needle biopsy was consistent with histiocytosis. Thyroidectomy was performed. A very invasive mass was encountered at the time of surgery. Histopathology result was consistent with an(More)
We report a case of huge pulmonary chondroid hamartoma in a 19-year-old female patient. The patient presented with progressive dyspnea and chest wall pain first noticed 2 years earlier. CXR and chest CT scan revealed a huge right hemithorax mass with extensive calcification. The pneumonectomy specimen from the right lung showed a huge mass with large(More)
BACKGROUND Diffuse malignant mesothelioma (DMM) is increasing in incidence on a worldwide basis and is linked to exposure to asbestos. Simian virus 40 (SV40), a DNA virus, was introduced inadvertently to human populations through contaminated polio vaccine during the years 1956-1963. It has been associated with various types of malignancy in animal(More)
BACKGROUND Minichromosome maintenance protein 6 (MCM6) is one of the six proteins of minichromosome maintenance family that are involved in the initiation of DNA replication and thus represent a marker for proliferating cells. The aim of this study was to determine the proliferation characteristics of neoplastic cells in patients with classic Hodgkin's(More)
Solitary extramedullary plasmacytomas are plasma cell tumors that tend to develop in mucosa-associated lymphoid tissues including the sinonasal or nasopharyngeal regions. Primary plasmacytoma of the lung is exceedingly rare and often presents as a solitary mass or nodule in mid-lung or hilar areas and diagnosed after resection. Herein, we report a case of(More)
Hemophagocytic lymphohistiocytosis (HLH) is still an important elusive and misdiagnosed condition despite of improved knowledge. Nephrotic syndrome associated with HLH is not a common feature and has been rarely reported in hemophagocytic syndrome. We report a 27-year-old man with HLH who progressed to multi-organ failure as well as nephrotic-range(More)
OBJECTIVE To better understand the characteristic morphology of angiogenic squamous dysplasia (ASD) and its association with different types of common bronchogenic carcinomas using routine white light bronchoscopy. METHODS Using a case-control design, 186 formalin-fixed paraffin-embedded blocks of bronchial tissue (136 cases, 50 controls) obtained from(More)
