[Environmental factors and iatrogenic elements in systemic scleroderma and related syndromes. Review of the literature]

Abstract

The etiology of scleroderma remains unknown. Although a genetic susceptibility seems to play a role, some environmental and iatrogenic factors have been suggested to trigger the disease. Contact for many months or years with natural or synthetic "toxic" products (by inhalation, cutaneous contact, injection, swallowing or surgical implant) could be implicated in the development of typical scleroderma or pseudo-scleroderma. These products are either occupational or non occupational like those used at home in daily life. We will sum up the knowledges about this subject.
