Materials and Methods
Among a total of 908 patients who underwent bronchoscopy at Samsung Medical Center from November 1994 to December 1995, anthracofibrosis was diagnosed in 28 patients. Diagnosis of anthracofibrosis was made solely on the basis of bronchoscopic findings. Patients in whom bronchoscopy revealed definite narrowing or obliteration of lobar or segmental bronchi with anthracotic pigmentations in the surrounding mucosa were considered to have anthracofibrosis and were included in this analysis. Patients
Results
Twenty patients had cough with variable amounts of sputum and 17 patients complained of dyspnea on exertion. Other complaints were fever, weight loss, general weakness/fatigue, chest discomfort, and hemoptysis (Table 1). Two patients were asymptomatic. These two patients were referred to our hospital because of radiographic abnormality on routine chest radiographic evaluation. The most common physical finding was wheezing sound on auscultation (8/28). Enlargement of peripheral lymph node was
Discussion
Characteristic features of the patients with bronchial stenosis due to anthracofibrosis in our study were as follows: (1) preponderance of older female patients; (2) no association with pneumoconiosis or smoking; (3) chief complaints of cough and dyspnea without constitutional symptoms; (4) segmental or lobar consolidation on simple chest radiographs; (5) abnormalities of bronchial airways with peribronchial cuffs of soft tissue or surrounding lymph nodes on chest CT; (6) most frequent
