[Chronic berylliosis of the lungs with special regard of pathomorphology (author's transl)].

The course of the disease of a berylliosis of the lungs is described with a patient, who had been working with berylliumoxide in the laboratory of a porcelain factory for about 21 months between his 16th and 20th year of life. At the age of 22 berylliosis was diagnosed radiologically and recognized as a occupational disease. At 32 years of age the patient died from the sequences of berylliosis. In this case-study the particular damages due to berylliosis are discussed depending on the different beryllium compounds. The chronic berylliosis of the lungs is pointed out in a pathologically anatomical way. It is supposed that an allergic reaction of the organism is reponsible for the pathogenesis. Special demands in the field of industrial medicine are resulting from the course of the disease.
