[Occupational vitiligo caused by para-tertiary-butylphenol, a trias of vitiligo, hepatosis and struma].

In the period between 1956-1974 twelve cases of occupational vitiligo due to para-tertiary butylphenol were observed. In addition another 12 cases of vitiligo of other etiology occurred. Occupational vitiligo cannot be distinguished from ordinary vitiligo. 21 patients had, aside from their leukodermia a normal thyroid function, and 18 patients showed symptoms of chronic liver damage. The trias of vitiligo, hepatic disease and struma euthyreotica was noticeable. Autoimmunisation tests were positive in cases of vitiligo of unknown etiology. The localization of vitiligo may be compared to viscero-cutaneous reflexes.
