[Autopsy-statistical analysis of multiple myeloma (author's transl)].

150 autopsies with multiple meyeloma were analysed. In about one third of the cases the multiple myeloma was diagnosed only at autopsy. Two thirds of the carriers of multiple myeloma were between 60 and 70 years old when they deceased. The osseous foci of multiple myeloma extended predominantly to the central parts of the skeletal system. In 120 patients the multiple myeloma was the cause of death. In half of these cases infections, particularly of the lung, had caused death. The second frequent cause of death was uraemia. 63 of the 150 multiple myeloma have been immunologically classified. The cases in question are 10 IgA-, 2 IgD-, and 42 IgG-multiple myeloma. Extraosseous foci of multiple myeloma appeared significantly more frequent in IgA-than in IgG-multiple myeloma. A haemorrhagic diathesis existed more frequent in IgA-multiple myeloma. Venous thromboses were more frequently to be found in IgG-multiple myeloma. Amyloid deposits and changes of the kidneys characteristic for the multiple myeloma appeared nearly in the same frequency in both types of multiple myeloma.
