Coexisting primary hyperparathyroidism and Albright's hereditary osteodystrophy--an unusual association.

Primary hyperparathyroidism associated with Albright's hereditary osteodystrophy was diagnosed in a 22 year old Japanese woman, the second such case to be reported. Albright's hereditary osteodystrophy (AHO) appears to be associated with a larger number of disorders than the well recognized pseudohypoparathyroidism. AHO and pseudo-pseudohypoparathyroidism are essentially identical.
