Was Paul Klee’s scleroderma an occupational disease? A series of historical and clinical vignettes,part III

Abstract

Paul Klee (1879–1940), one of the most influential artists of the 20th century, died at 60 years of age from complications of systemic sclerosis (scleroderma). The precipitating event(s) of Klee’s scleroderma, as in most cases, will never be known. Among various potential factors, exposure to heavy metals, crystalline silica, and organic solvents—acting alone or in combination—can now be considered potential factors in the onset of Klee’s disease. By altering and modulating epigenetic determinants in a genetically susceptible host, these and other environmental factors may have led to perturbations of self-tolerance and inflammation culminating in Klee’s scleroderma.
