[Vitiligo from p-tert. butylphenol; a contribution to the problem of the internal manifestations of this occupational disease].

10 worker suffering from occupational vitiligo due to p-tert. butyl phenol have been observed in an Austrian resin factory. The dust concentration and its content of p-tert. butyl phenol in the working area were measured. On the basis of these results preventive measures were taken to reduce the exposure of the workers to p-test butyl phenol. In the presented cases an involvement of internal organs--as described by Rodermund et al. (1975)--could not be observed.
