Abstract
Long R, Wong E, Barrie J(AQ1) ronchial narrowing or obliteration with black pigmentation of overlying mucosa has been termed “anthracofibrosis” [1]. Its occurrence in nonsmoking Koreans, especially women, who have had no occupational exposure to coal dust but who were possibly exposed to wood smoke has been associated with tuberculosis (TB) [1, 2]. Anthracofibrosis is said to occur in other Asian populations and blacks, but no documentation of this is available to our knowledge, nor are reports of this syndrome in Asian or black immigrants to North America. The response of anthracofibrosis-related TB to antituberculosis drugs is unknown. In Alberta, a province of Canada that accepts more than 15,000 new immigrants annually, we diagnosed two cases of anthracofibrosis-related pulmonary TB in adult female immigrants from East India. These cases constituted 7.7% (2/26) of all culture-positive pulmonary TB cases diagnosed in adult (≥14 years), female, foreign-born persons in the province in calendar year 2002. We report the pretreatment and posttreatment contrast-enhanced CT scan and bronchoscopic findings of this syndrome.
