[Case report: adenocarcinoma of the kidney developing metastzsizing to both lungs, with numerous microliths radiologically imitating Microlithiasis alveolaris pulmonum (author's transl)].
A 28 years old man developed a radiological pattern like Microlithiasis alveolaris pulmonum during the following five years after exstirpation of his right kidney due to an adenocarcinoma. Tests showed, in contrast to the x-ray pulmonary function, only a slight restriction of total lung capacity over a long time up to few months before he died. Autopsy showed a spread of miliary and submiliary metastases in the lower parts of both lungs. In all metastases psammomabodylike microliths were found microscopically, especially numerous and enlarged with both lungs. A second check of the slides of the primary tumour showed rare microliths too, not mentioned at that time. A microlith producing tumour of the kidney was first published with full details by Lubarsch in 1925. The radiological aspect of the lungs of the reported case reveals serious differential diagnostical problems to Microlithiasis alveolaris pulmonum.
