[Black smoke lung disease – a new disease in Sweden]

Black smoke lung disease - a new disease in Sweden We describe two elderly female patients, immigrants to Sweden from Afghanistan, with intensive longtime exposure to smoke from biomass, and who presented with bronchial stenosis and severe bronchial obstruction. CT and X-ray showed bizarre perihilar infiltrates in the lungs. Bronchoscopy revealed black narrow bronchi with a middle lobe stenosis in one of the patients. These findings indicate the diagnosis bronchial anthracofibrosis (BAF). The here described findings are seen mainly in elderly never-smoking women from developing countries who have spent years cooking food in poorly ventilated kitchens. With increased immigration from these countries such cases will be seen in industrialized countries as well. Active tuberculosis must always be excluded but otherwise no more active investigations such as biopsies are warranted. We suggest that this disease should be termed »black smoke disease« to differentiate it from coal workers' pneumoconiosis, silicosis, and other classical occupational diseases which can have similar clinical and radiological pictures. This term is easily understood even by non-medical persons and illustratess both the etiology and the black bronchi.
