Camptodactyly, polyepiphyseal dysplasia and mixed crystal deposition disease

A sporadic case of camptodactyly and arthropathy is described in a 54-year-old man. Polyepiphyseal dysplasia complicated by the so called "chondrodysplastic rheumatism" was a main feature of the arthropathy which included early onset osteoarthritis, calcium pyrophosphate dihydrate and calcium phosphate deposition diseases. We suggest that epiphyseal dysplasia, chondrocalcinosis and mixed crystal deposition disease could be an additional cause of a camptodactyly-arthropathy syndrome.
