Pneumoconiosis is the disease resulting by the inhalation of dusts in the lung, and pulmonary tuberculosis is the disease involved by the infection of the tubercle bacilli in the lung.<BR>It has been discussed that development of pulmonary tuberculosis is affected b y inhalation of silica dusts. Concerning the relationship of silicosis and pulmonary tuberculosis, it was reported that two types of "Complication form" and "Combination form" were observed pathologically by Prof. Husten. Since then, many reserches have been reported on the relationship of pneumoconiosis and tuberculosis.<BR>It is well known that prognosis of the pneumoconiotuberculosis is not so good as that of the each disease.<BR>In this paper, the pneumoconiotuberculosis was discussed epidemiorogically, clinically, pathologically and experimentally. In epidemiological aspect, the results of the mass survey in the factory of dust circumstances were stated. It was emphasized that complication of pneumoconiosis and pulmonary tuberculosis was much more detected. In the clinical and pathological aspects, the more severe complex lesion was often formed in the pneumoconiotuberculosis. And it was more resistant to medical treatment than simple tuberculosis. In the experimental aspect, cavity formation involving a great deal of caseous substances was often observed after the infusion of dust particles (free silica, talc, and kaolin) with tubercle bacilli. Much more tubercle bacilli were counted in the pneumoconiotuberculous lesion than in simple tuberculous lesion.<BR>It is new ly recognized that pneumoconiotuberculosis is an important occupational respiratory disease. As pneumoconiotuberculosis is a difficult curable disease, it must be efficiently careful to treat pneumoconiotuberculosis.
