Abstract

Objectives : Endobronchial anthracofibrotic pigmentation, which presents as dark black or brown pigmentation mucosal changes of multiple bronchi combined with bronchial fibrosis and obstruction, is not a rare finding when performing diagnostic bronchoscopy for Koreans. This study was performed to define the clinical characteristics and to determine the association of these finding with the Korean life style and such other diseases as coal workers, pneumoconiosis or tuberculosis in the patients with anthracofibrotic pigmentation. Methods : This retrospective analysis was conducted on 70 (5.2%) patients with endobronchial anthracofibrotic pigmentation, among a total of 1340 patients who underwent bronchoscopy. The distinctive clinical features, the personal life style, the past medical history, the histology and microbiology, the radiologic finding and the natures of the bronchoscopic lesions were analyzed. Results : This mean age of the patients with anthracofibrotic pigmentation was $60.6{\pm}9.2$ year old and the male to female ratio was 1:1.7. The common respiratory symptoms of these patients were coughing and sputum (81%, 57/70), and this was followed in order by dyspnea and hemoptysisir. The symptoms were not related with smoking and an occupational history such as being a coal worker and so on. Pneumonia was most common finding on the radiologic studies. On bronchoscopy, the right middle lobe bronchus was most commonly involved. The most common associated disease was tuberculosis, and 40 cases (57.1%) were diagnosed by AFB staining, TB PCR, bronchoscopic guided tissue biopsy and a past history of tuberculosis. Other diseases related with anthracotic pigmentation were hypertension, diabetes, COPD, lung cancer, pneumoconiosis and asthma. Conclusion : These results suggest that endobronchial anthracofibrotic pigmentation was mostly related with pulmonary tuberculosis rather than with coal- related disease. Endobronchial anthracofibrotic pigmentation was more prevalent in older age females in Korea.

목 적: 기관지 탄분 섬유화증은 국내에서 드물지 않게 관찰되는 특징적인 소견으로, 기관지 내시경상 기관지내 탄분 침착 및 협착 소견이 관찰된다. 이는 외국의 보고에서는 찾아보기 힘든 병변이며, 아직 결핵과의 관련성만 추측할 뿐 뚜렷한 원인이나 발병기전에 대해 알려진 바는 없다. 이에 본 저자들은 기관지 내시경상 탄분 침착을 보이는 환자들의 임상양상 및 연관된 질환을 알아보고자 본 연구를 시행하게 되었다. 방 법: 2000년부터 2004년까지 건양대학교 병원에서 기관지내시경 검사를 시행한 환자 1340명중에서 기관지 탄분 섬유화증의 병변이 기술된 70명(5.2%)의 환자의 임상양상 및 최종 진단을 확인하여 후향적으로 분석하였다. 결 과: 대상자의 평균연령은 $60.6{\pm}9.2$세로 대부분 고령이었고, 여성이 44명(62.9%)으로 남성26명(37.1%)보다 많았다. 탄분증과 흡연의 관계는 비흡연가가 56명, 흡연가가 14명으로 비흡연가가 흡연가에 비해 4배정도 많아 탄분증과 흡연은 관계가 없는 것으로 보였다. 거주지를 도시와 농촌으로 비교하였을 때 도농간 차이는 보이지 않았다(34명 vs 36명). 기타 특별한 사회 인구학적 차이는 없었다. 입원 당시 환자들의 증상은 대부분 기침이 주된 증상이었다. 기관지 내시경상 기관지 폐쇄 소견을 보인 환자는 21명(30.0%)이었고 주로 우상엽과 우중엽부위가 많았다. 최종 진단으로는 객담 항산균 검사 및 조직소견(PCR포함) 등으로 확진된 결핵이 34례(48.6%)이고, 나머지 환자 중에 과거에 결핵을 앓은 병력이 있는 환자가 6례로 총 40례(57.1%)에서 결핵과 연관성을 확인할 수 있었다. 그 밖에 고혈압 15례(21%), 당뇨병 9례(13%), 만성폐쇄성 폐질환 7례(10%), 폐암 6례(8.6%), 진폐증 1례(1.4%), 천식 1례(1.4%)로 나타났다. 결 론: 기관지 내시경상 기관지 탄분 섬유화증의 병변은 5.2%의 유병률을 보였으며, 고령의 여자에서 높은 빈도를 보이며, 57.1%에서 결핵과는 연관성이 있었다.
