Coexisting hyperparathyroidism, renal osteodystrophy and psoriatic arthritis.

We report the case of a 60-year-old woman with hyperparathyroidism, renal osteodystrophy and psoriatic arthritis. The coexistence of findings of hyperparathyroidism and renal osteodystrophy has been described and there are also reports of patients suffering from renal arthropathy mimicking hyperparathyroidism. To our knowledge, there is no description to date of a case displaying findings of the co-occurrence of these conditions in a patient. We would like to emphasize that attention should be paid to the possible diagnosis of a coexisting inflammatory rheumatic disease when rheumatological symptoms of recent onset occur in patients with long-standing renal osteodystrophy and/or symptoms mimicking hyperparathyroidism occur in these patients.
