[Polymorphism of articular chondrocalcinosis].

The articular chondrocalcinosis--conditioned by the formation of crystals of calcium pyrophosphate dihydrate in the joint cartilage--increasingly gains clinical interest. The symptomatology is multivariant: mono-, oligo- and polyarticular with simultaneous localisation in the discs. Characteristic, but not proving, is the calcification demonstrated in the X-ray picture.
