[The frequency of intravital not detected tuberculosis in autopsies (author's transl)].

The analysis of 41 576 autopsies in the years from 1962 till 1978 revealed a total amount of 872 cases of active tuberculosis. In this time the percentage of tuberculosis mortality decreased from 3.3% (1962) to 0.9% (1978) of all autopsies. An increase of ante mortem not detected cases of tuberculosis with a high rate of generalised miliar tuberculosis could be demonstrated in our observations. Especially in high age patients exacerbations of tuberculosis should be considered. In diseases with clinical symptoms of the hematopoetic system tuberculosis should be taken into considerations of differential diagnosis.
