Abstract
The association of pseudogout with hyperparathyroidism and gout have been reported by many researchers. According to Mc Carty, the incidence of the association between pseudogout and hyperparathyroidism is 7.2%, however, Resnick or Bjelle found no association between the two diseases.
Pseudogout has another association with gout, an incidence of from 8% to 0%. There have been no reports on the association between pseudogout and hyperparathyroidism or pseudogout and gout in Japan. However, we have experienced a case of pseudogout associated with hyperparathyroidism and gout.
The clinical features of the case were of great interest, and are discussed in the attached paper. The reason for this association remains obscure, however, though it suggests that some underlying predisposition to crystal deposition is common to these three diseases.
