anthracofibrosis

BACKGROUND: Non-small cell lung cancer (NSCLC) patients without lymph node (LN) metastases (pN0) may exhibit different survival rates, even when their T stage is similar. This divergence could be attributed to the current pathology practice, wherein LNs are examined solely in two-dimensional (2D). Unfortunately, adhering to the protocols of 2D pathological examination does not ensure the exhaustive sampling of all excised LNs, thereby leaving room for undetected metastatic foci in the unexplored depths of tissues...

A rare case of a patient with chronic obstructive pulmonary disease who developed secondary anthracofibrosis to biomass exposure, fibrosing mediastinitis due to anthracotic enlarged lymph nodes in the mediastinum, and pulmonary hypertension because of compres- sion of the lymph nodes on the pulmonary arteries is presented. This is a case report of a 71-year-old female patient who has been followed up with chronic obstructive pulmonary disease for 10 years, has no history of smoking, and has been exposed to biomass for many years...

We present the case of a 78-year-old female undergoing pulmonary endarterectomy (PEA) because of suspected chronic thromboembolic pulmonary hypertension (CTEPH). During surgery firm black masses were encountered in the aortopulmonary window and on the cranial part of the right pulmonary artery (PA). After PA arteriotomy we visualized intraluminal black firm stenosing plaques at the orifices of the three right and of the left lingular and lower lobar branches. Since no dissection plane could be obtained the procedure was discontinued...

PURPOSE: A subset of asthmatics suffers from persistent airflow limitation, known as remodeled asthma, despite optimal treatment. Typical quantitative scoring methods to evaluate structural changes of airway remodeling on high-resolution computed tomography (HRCT) are time-consuming and laborious. Thus, easier and simpler methods are required in clinical practice. We evaluated the clinical usefulness of a simple, semi-quantitative method based on 8 HRCT parameters by comparing asthmatics with a persistent decline of post-bronchodilator (BD)-FEV1 to those with a BD-FEV1 that normalized over time and evaluated the relationships of the parameters with BD-FEV1...

It has been stated that bronchial anthracofibrosis (BAF) has an important relationship with pulmonary tuberculosis (TB), and the coexistence of TB and BAF is high. The purpose of this study was to compare the differences in computed tomography (CT) characteristics of pulmonary TB according to the presence of underlying BAF. Total of 202 consecutive patients who were diagnosed with pulmonary TB and underwent bronchoscopy and CT in our institution were retrospectively reviewed. We classified the patients into two groups according to the presence of BAF and compared the clinicoradiological findings between the two groups (anthracofibrosis group vs...

Objective: Anthracosis is defined as deposition of black pigments in the bronchial mucosa or lung parenchyma. The aim of this study was to investigate the clinical features of patients with coexisting anthracosis and interstitial lung diseases (ILDs). Methods: A total of 335 ILDs patients who underwent bronchoscopy at the affiliated hospital of Qingdao University were included in our study. We enrolled 71 patients who diagnosed with anthracosis by bronchoscopy. The clinical presentations, radiographic features, and bronchoscopic findings of the patients were reviewed...

To determine the ultrasound imaging characteristics of patients with bronchial anthracofibrosis (BAF) and identify clinical markers for prevention and treatment. We randomly selected 1243 participants (113 with BAF) who underwent bronchoscopy and received treatment at our institution between April 2018 and October 2019. BAF was classified as flat, deep-seated retracted, or black mucosal protruding based on microscopic findings. Ultrasound probes were used to determine the maximum thickness of the tube walls and submucosa...

BACKGROUND: Bronchial anthracofibrosis is a common disease that has been reported in the past. We aim to summarize the clinical characteristics of bronchial anthracofibrosis combined with tuberculosis infection to reduce missed diagnosis. METHODS: The clinical features of two cases of bronchial anthracofibrosis combined with tuberculosis were analyzed retrospectively, and relevant studies were reviewed. RESULTS: The two patients were both elderly individuals who presented with chronic cough and expectoration...

Bronchial anthracofibrosis is a rare disease defined as bronchial stenosis with black pigmentation and usually not associated with artery occlusion. The patient was an 81-year-old man with silicosis. He presented with dyspnea on exertion, and pulmonary hypertension due to right upper pulmonary artery occlusion without thromboembolism was diagnosed on the basis of the results of right heart catheterization and pulmonary angiography. Bronchoscopy demonstrated bronchial anthracofibrosis in the right upper lobe...

BACKGROUND: Tracheobronchomalacia (TBM), presenting with the softening of the walls of trachea and bronchi, can cause respiration problems. Despite the importance of TBM, data on its prevalence and related factors are limited. In the current study, the prevalence and predictive factors of this illness were investigated. METHODS: This cross-sectional study was conducted on patients who were bronchoscopy candidates in the diagnostic department of pulmonary diseases in Afzalipour hospital in Kerman, Iran, from May 2017 to May 2018...

Background: Anthracosis and anthracofibrosis are attributed to the deposition of carbon particles along with fibrosis, adhesion, narrowing, and collapse. There has been no study on the characteristics of the pleural fluid in anthracosis. The present study analyzed the biochemical characteristics of pleural effusion in patients with pulmonary anthracosis. Patients and methods: The study is a cross-sectional study which included patients who were referred to the Afzalipour Hospital in Kerman, eastern Iran...

BACKGROUND: Endobronchial lung cancer (EBLC) and bronchial anthracofibrosis (BAF) share similar symptoms and radiological findings. The aim of this study was to describe clinical and radiological differences between BAF and EBLC, both of which were confirmed by bronchoscopy. METHODS: This was a retrospective study of patients with BAF or EBLC from 2008 to 2014. Data were derived from a bronchoscopy registry made since January 1, 2008. Clinical and radiological characteristics of both diseases were analyzed...

Anthracosis is associated with smoking, air pollution, tuberculosis infection, and exposure to biomass. Anthracosis commonly involves bronchial trees and rarely lymph nodes. We report an unusual case of a 44-year-old female presented with painless supraclavicular swelling for 1 month. A fine-needle aspiration cytology examination was done from the swelling. The smears were markedly cellular and showed the presence of sheets, clusters, and singly scattered round to oval cells with mild anisonucleosis, fine to coarse chromatin, few with tiny nucleoli, and cytoplasm containing abundant black coarse pigment...

OBJECTIVE. The purpose of this article is to evaluate the accuracy of and complications with CT-guided percutaneous core needle biopsy (CNB) of thin-walled cavitary pulmonary lesions. MATERIALS AND METHODS. This retrospective study involved 32 CNBs in 30 patients who had thin-walled cavitary pulmonary lesions (wall thickness < 5 mm) and underwent CT-guided CNB. After the 30 patient records were evaluated for the diagnostic accuracy, sensitivity, and specificity of CT-guided CNB, the results were compared with the final diagnosis after surgery or clinical follow-up...

A 73-year-old female living in the rural area presented with chronic cough. She had multiple rounded nodules less than 1cm in size in both lungs, and bilateral mediastinal lymphadenopathy in chest images, which could be confused with metastatic cancer. Bronchoscopy did not show bronchial anthracofibrosis, and positron emission tomography (PET) scan showed F-18 fluorodeoxyglucose (18 F FDG) uptake. Surgical biopsy histology confirmed that the nodule was anthracofibrosis and the lymph node was reactive hyperplasia...

Prolonged exposure to biomass fuel smoke is a proven irritant, known to aggravate chronic lung diseases. Of the myriad spectrum of thoracic manifestations associated with inhalation of biomass fuel smoke, bronchial anthracofibrosis is a recently described entity characterized by bronchial narrowing and visible anthracotic pigmentation on bronchoscopy. Common imaging features include bronchostenosis, peribronchial soft tissue with or without calcification along with peribronchial lymph nodes. Its close similarity to endobronchial tuberculosis and bronchogenic carcinoma in clinical presentation and imaging poses a diagnostic challenge and hence underlines the importance of knowledge about this entity...

A fifty-eight-year-old, nonsmoker Indian male presented with recurrent left pleural effusion. He had history of dry cough, exertional breathlessness for the last two years. He denied any occupational exposure or second hand smoke exposure. His physical examination demonstrated decreased breath sounds on the left side of chest. Cardiac evaluation was unremarkable. Diagnostic pleural aspiration revealed straw coloured fluid, exudative, and nonmalignant in nature. CT-imaging of the chest demonstrated left pleural effusion, nodular parenchymal infiltrates in bilateral lungs, plate like atelectasis in the left lower lobe...

PURPOSE: Anthracosis, a form of pneumoconiosis commonly caused by air pollution and other environmental factors, is a new entity in respiratory disorders. Bronchoscopy and transbronchial lung biopsy (TBLB) are the gold standard of diagnosis. Herein, we evaluated the results of bronchoscopy and chest computed tomography (CT) scans of 187 anthracotic patients. MATERIAL AND METHODS: Between April 2016 and April 2017, 187 cases (99 males, mean age 65 ± 10.2 years) who underwent flexible bronchoscopy and TBLB for various indications were considered for this study...
