[Coincidence of silicosis and sarcoidosis. 2. Relations between silicosis and sarcoidosis as well as forensic consequences].

The observation of a coincidence of silicosis and sarcoidosis (see the 1st Communication) raises many problems on the pathogenesis of both diseases, their possible causal connections and not last the medical judgement. The mutual influence of both diseases is not discernible in the particular case. Pathogenetic connections derived from mentioned examples of coincidence of silicosis and sarcoidosis stay hypothetical, because its experimental confirmation cannot be realized. Within the medical judgement of the coincidence of silicosis and sarcoidosis the differentiation of injury caused only by silicosis must be tried. If that is not possible, the whole bodily injury must be imposed to silicosis to protect the patient from a disadvantageous expert opinion. The professional activity of patients with sarcoidosis in an atmosphere of quartz dust is not permissible, because the momentary injury of tissues of lung and lymph nodes as well as the prognosis of sarcoidosis are not definable with the actual available methods, but it is safe to say, that silicosis is an additional danger to the patient.
