[Silicotuberculosis in Austria and the industrial injuries act (author's transl)]

The case material comprising all persons who developed silico-tuberculosis since it was listed as an occupational disease almost 50 years ago is analysed. The relationship between various occupations and the incidence of silicosis is reviewed with special reference to the most exposed group: the wokers in the granite quarries of Upper Austria. The changes in the clinical picture of the lesion, legal aspects, diagnostic difficulties in distinguishing between silicosis with or without complicating tuberculosis are discussed.
