INTRODUCTION Anthracosis of the lung is the blackening of bronchial tissues which can lead to chronic bronchial obstruction. Many studies have shown association of bronchial anthracosis and tuberculosis. The aim of this study was accumulation of scattered studies and getting the definite conclusion about the association between anthracosis and tuberculosis. MATHERIALS AND METHODS We conducted...

BACKGROUND Anthracosis is the black pigment discoloration of bronchi with an unknown cause which can cause bronchial destruction and deformity (anthracofibrosis). The objective of this study was to determine the frequency of tuberculosis in anthracosis and evaluate their association. METHODS One hundred and twenty subjects with bronchoscopy diagnosis of simple anthracosis, anthracofibrosis an...

BACKGROUND There are many reports on the association between anthracosis and tuberculosis. This study focuses on bronchial anthracosis and associated diseases in the province of South Khorasan-Iran. METHODS This case-series study is performed on patients referred to the Vali-e-Asre Hospital (South Khorasan-Iran) for bronchoscopic evaluations during the period of 2009-2012. Written informed co...

BACKGROUND A probable concordance and association between pulmonary tuberculosis and anthracosis was observed in the published literature. We conducted this study to evaluate the clinical and radiologic characteristics of patients with bronchoscopic evidence of anthracosis as well as the prevalence of pulmonary tuberculosis in patients with anthracosis. METHODS Included in the study were 150 ...

PURPOSE We demonstrate the multislice computed tomography (MSCT) findings of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)-proven hilar and mediastinal lymph node enlargement with signs of anthracosis. MATERIALS AND METHODS 53 enlarged lymph nodes in 39 patients (28 male, 11 female) with EBUS-TBNA-confirmed anthracosis were analyzed retrospectively. RESULTS Th...

The association between indoor smoke exposure due to traditional baking (baking homemade bread) and anthracosis has rarely been investigated. The aim of the present study is to quantify such association among the Iranian population. A hospital based case-control study was carried out on 83 anthracotic cases and 155 controls (83 individuals with non-anthracotic pulmonary disorders from the pulmo...

OBJECTIVES Occupational exposure to carbon, silica, and quartz particles are predisposing factors for bronchial anthracosis. In some cases anthracosis may be associated with mycobacterium tuberculosis. This study aims to investigate the clinical, radiographic, and bacteriologic findings in bronchial anthracosis patients and its association with tuberculosis. METHODS This is a prospective stud...

Bronchial anthracosis was recently defined in the English radiology literature as a luminal narrowing associated with anthracotic pigmentation on bronchoscopy without a relevant history of pneumoconiosis or smoking. Anthracosis refers to the presence of carbon particles in the lungs, not to a disorder per se. Anthracofibrotic lesions carry the potential risk of massive hemorrhage during endobro...

The p16 (CDKN2/MTS-1/INK4A) tumor-suppressor gene is frequently inactivated by DNA methylation in lung carcinomas. To clarify whether background anthracosis may play a role in DNA methylation and inactivation of the p16 gene, we examined DNA methylation of the p16-promoter region by methylation-specific polymerase chain reaction, and p16 expression immunohistochemically, and compared the result...
