title: Intra-articular calcification in progressive systemic sclerosis.
abstract: Subcutaneous and periarticular dystrophic calcifications are well known to be associated with progressive systemic sclerosis (PSS). On the other hand, calcifications inside the joints are very rarely reported. We report a new case of this unusual complication of PSS. The observation of the complete radiological follow-up led us to propose a mechanical rather than a purely inflammatory pathogenetic mechanism of this complication.
