Osteosclerosis in a thirty-four-year-old woman with primary hyperparathyroidism.

Hyperparathyroidism is an endocrine abnormality that frequently causes diffuse osteopenia in the bones. Osteosclerosis is a rare phenomenon in adults with primary hyperparathyroidism since the usual skeletal manifestation is generalized osteopenia. We describe a patient with generalized osteosclerosis in the jaws and skull in association with primary hyperparathyroidism, while the other skeletal bones had normal or decreased density.
