The objectives of this study were: 1) to evaluate the prevalence of ErS in our SSc cohort; 2) to characterize the cases; 3) to evaluate the clinical and laboratory characteristics of SSc in patients with (Ers) or without silica exposure.

Data on professional activity and possible exposure to silica were obtained by phone interview. Results: Among 48 patients with SSc, the prevalence of ErS was 16.7% (8/48). All cases identified were male, corresponding to 72.7% of men with SSc followed at our department. There was a statistically significant association between ErS and male gender (p
