Arthropathie de Jaccoud et chondrocalcinose articulaire: Une association rare

Jaccoud's arthropathy [JA] is a chronic deformity affecting hands and feet, which are voluntarily correctable by the patients. JA was usually reported in assocation with rheumatic fiver and systemic lupus erythematosus. We describe an exceptional association between a pyrophosphate arthropathy and JA of the hands. It is a 48 year old woman, having a 13 years history of polyarthritis involving shoulders, elbows, hips and knees, and 4 years after, a progressive under deviation of the fingers of the hands. Calcium pyrophosphate dihydrate crystals were identified in the synovial knee biopsy. Hands xrays as RMI don't identify erosions and confirmed the JA
