“…In Korea, earlier study by Chung et al,[2] reported frequency as high as 60% of tuberculosis in anthracofibrosis, but recent studies in this country reported frequencies in a range of 20-34%. [6][7] One decade ago, in our region, frequency of tuberculosis was reported in 30% of anthracofibrosis subjects,1 but in present study and a large recent study in Iran by Amoli,8 its frequency declined to approximately 27%. In developed countries, tuberculosis in anthracofibrosis is even lower while Wynn et al reported tuberculosis in only one anthracofibrosis subject in England.9 Overall frequency of tuberculosis in anthracofibrosis subjects during routine bronchoscopy in recent studies were in a range of 20-30%.…”

BackgroundAnthracosis 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.MethodsOne hundred and twenty subjects with bronchoscopy diagnosis of simple anthracosis, anthracofibrosis and non-anthracotic control groups entered this study. Demographic data and important clinical and radiological findings were recorded. Bronchial biopsy and bronchoalveolar lavage were performed for further cytopathological, acid-fast bacilli staining and culture in all cases.ResultsCough and dyspnea were significantly higher in anthracosis subjects. Radiological characteristic of tuberculosis such as upper lobe localization and cavity were not significantly higher in anthracosis subjects that suffer from tuberculosis. Laboratory test for tuberculosis showed positive acid fast bacilli in 17.5 and 25% and caseating granuloma in 20 and 17.5% of anthracosis and anthracofibrosis subjects. Adding the result of culture, the frequency of tuberculosis in both groups of anthracosis was 27.5% that was significantly more than nonanthracotic control group (Odd ratio= 6.15, CL=1.29

“…FDG PET/CT showed increased uptake at the hilar lymph node, but no significant uptake at the obstruction site, suggestive of benign aetiology. FOB showed anthracotic pigmentation and stricture, suggestive of anthracofibrosis [23]. Follow-up chest CT 2 years later showed no interval change in the stricture and distal collapse.…”

BackgroundEndobronchial tuberculosis (EBTB) is a special form of pulmonary tuberculosis. In spite of much progress in the diagnosis of this disease in past years, delayed or mistaken diagnosis is still commonly seen.ObjectiveThe aim of this study is to try to find out some useful clues for the diagnosis of EBTB, especially the early diagnosis.MethodsThe medical records of patients with EBTB were analyzed retrospectively. Results: The male-to-female ratio was 1:2.2 out of 22 patients. Patients aged below 60-years-old constituted 72.7% of the cases. 22.7% of these patients were smokers. The male-to-female ratio of smokers was 4:1. 68.2% of these patients tested all showed negative result for the HIV test. The frequent complaints were cough, sputum, shortness of breath and fever, and antibiotic treatments were usually inefficacious. Multiple lobes lesion, exudative shadow and atelectasis were the frequent radiological findings. Acid-fast bacilli staining for sputum smear was positive in only 13.6% of these patients. Tuberculin skin test was positive in 59.1% of these patients. Granular lesion was the most common bronchoscopic appearance in these patients. Histological changes showed distinctive tuberculose lesion in 72.2% of 18 patients undergoing bronchoscopic biopsy.ConclusionThe diagnosis of EBTB is easily delayed or mistaken because of nonspecific clinical manifestations and the low incidence of positive acid-fast bacilli staining. A high index of awareness of this disease is required for diagnosis. Bronchoscopy should be performed as soon as possible in suspected patients, especially when patients present positive tuberculin skin test or no response to antibiotic treatments.

CT Differentiation of Anthracofibrosis from Endobronchial Tuberculosis

Abstract: Anthracofibrosis can be differentiated from endobronchial TB on CT. Furthermore, CT is helpful in the diagnosis of anthracofibrosis before bronchoscopy is performed.
