[Diffuse articular chondrocalcinosis and Paget's disease]

At the time of a personal observation of Paget's disease associated with a diffuse articular chondrocalcinosis (ACC) in a 75-year-old man suffering from diabetes and hyperuricaemia, the authors re-examined 61 patients suffering from Paget's disease to look for this association which had been previously mentioned by Radi et al. with the unusual frequency of 42 percent of cases. In 52 percent of their patients, who had undergone complete radiological examination of the skeleton, the authors found only one case of ACC, or 1.9 percent. Taking into account the respective frequencies of Paget's disease and of diffuse ACC in the general population aged more than 40 years, the results of this careful study led the authors to conclude that an association of ACC and Paget's disease is due to chance.
